Abstract

Functional material of iron oxide (Fe2O3) nanoparticles-functionalized Hydroxyapatite (HA) was synthesized from chicken bone waste. The preparation of material involved the calcination of chicken bone waste followed by the dispersion of iron oxide precursors and hydrothermal treatment to get coprecipitated HA. Systematic physicochemical characterization was performed by various analytical techniques, including scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Raman spectroscopy, and diffuse reflectance UV-Visible spectroscopy. The photocatalytic activity of the composite was examined to degrade methylene blue under various photon sources and pH condition. The results demonstrated that a high crystalline Fe2O3/HA was derived, and detail of the analysis confirm the functionality of iron as dopant in the crystalline structure of HA and the dispersed photoactive nanoparticles. Photocatalytic degradation experiments resumed that the high degradation efficiency could be achievable at alkaline condition and under visible light illumination, as the efficiency of 78.88% was the optimum value.

Abstract

Iron oxide-loaded porous carbon has demonstrated effectiveness in heterogeneous Fenton reactions for degrading antibiotic pollutants in wastewater. However, the effect of calcination temperature on the properties of iron oxide loaded in biomass-derived carbon as a catalyst support remains largely unknown. In this work, sugar palm fiber served as the carbon source, and iron wet impregnation followed by calcination was employed to synthesize the catalyst. Calcination temperatures of 300, 500, and 700 °C were systematically investigated. Comprehensive characterization using TGA, XRD, SEM-EDX, VSM, Photoluminescence, Raman spectroscopy, nitrogen sorption analysis using NOVA and AUTOSORB instruments indicated that increasing the calcination temperature to 700 °C resulted in higher surface area, optimal pore structure, enhanced Fe3O4 formation, increased graphitization, and improved iron oxide dispersion. Catalytic tests for the degradation of 10 ppm levofloxacin showed that catalysts prepared at higher calcination temperatures exhibited superior removal efficiency and recyclability.

Abstract

In this study, a sustainable mesoporous silica material was synthesized using gelatin as a co-template (GSBA-15), followed by the incorporation of iron oxide (Fe₂O₃) to enhance its adsorption performance toward methylene blue (MB) and methyl orange (MO). Tamarindus indica pulp extract (TIE) was employed as a natural and environmentally benign activating agent, providing organic functionalities that facilitated material synthesis and surface modification. The adsorption performance of the synthesized materials, namely GSBA-15 and Fe₂O₃/GSBA-15-TIE, was evaluated using UV–Vis spectrophotometry. Under optimal adsorption conditions, the maximum adsorption capacities for MB were 176.062 and 183.497 mg.g⁻¹ for GSBA-15 and Fe₂O₃/GSBA-15-TIE, respectively. For MO, the corresponding adsorption capacities were 15.582 and 16.000 mg.g⁻¹. Kinetic studies revealed that the adsorption of both dyes was best described by the pseudo-second-order model, suggesting that chemisorption played a dominant role in the adsorption process. The enhanced adsorption performance of Fe₂O₃/GSBA-15-TIE compared with pristine GSBA-15 demonstrates the beneficial effects of iron oxide incorporation and TIE activation. These findings highlight the potential of Fe₂O₃/GSBA-15-TIE as a sustainable and efficient adsorbent for dye removal in wastewater treatment applications.

Abstract

The contamination of aquatic environments by synthetic dyes such as Rhodamine B (RhB) represents a growing environmental and public health concern. In this work, a bismuth silicate composite (Bi2SiO5) was successfully synthesized via a rapid microwave-assisted co-precipitation route using silica extracted from natural Tunisian sand as a sustainable and low-cost precursor. The material was systematically characterized by XRD, FTIR, UV-Vis DRS, SEM, TEM, and EDX analyses, revealing a highly crystalline orthorhombic structure with an average crystallite size of 57.1 nm (Debye–Scherrer), primary particle dimensions of approximately 43.1 nm, and an optical bandgap of 2.74 eV. Under simulated solar irradiation, Bi2SiO5 achieved near-complete decolorization (≈ 99 %) of RhB within 15 min and a significant Chemical Oxygen Demand (COD) removal efficiency of 75 % after 50 min, demonstrating substantial organic scaffold breakdown. Non-linear Kinetic analysis revealed that RhB degradation followed pseudo-first order (PFO) kinetics (k1 = 0.142 min-1, R2 = 0.962). Radical Scavenger experiments identified •OH and •O2- as the dominant reactive species, with h+ playing a secondary role, indicating a radical-mediated oxidative degradation mechanism. Bi2SiO5 demonstrated good reusability over five consecutive cycles, retaining 95% RhB removal efficiency after the fifth run. These findings establish Bi2SiO5 as a promising, eco-friendly photocatalyst derived from abundant natural resources for solar-driven wastewater remediation.

Abstract

series of catalysts, including date seeds (DS), NiO/DS, Ru2O3/DS, and bimetallic NiRu2O4/DS, anchored on a date seed-derived carbon support. The newly synthesized catalysts were characterized using Fourier Transform Infrared (FTIR), NH3/CO2-temperature programmed desorption (TPD-NH3/CO2), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), Field Emission Scanning Electron Microscopy (FE-SEM), Transmission Electron Microscopy (TEM), Thermogravimetric Analysis (TGA), and X-ray photoelectron spectroscopy (XPS) techniques. Structural analysis confirmed that the metal nanoparticles were successfully embedded within the porous matrix of the biomass support, which significantly augmented both the surface area and the density of active sites. At optimized parameters of 350 °C and 40 bar N2 over a 3 h period, the NiRu2O4/DS catalyst achieved a maximum hydrocarbon yield of 95%. Detailed chemical profiling of the liquid product showed a high selectivity toward n-Tetradecane (C14) and n-Heptadecane (C17), both critical precursors for bio-jet fuel production. The remarkable performance of the catalyst is fundamentally driven by a synergistic combination of its structural and chemical properties: a higher BET surface area compared to the DS support (4.42 m2/g), a substantial pore volume of 0.0137 cm3/g, and a moderate surface basicity of 8534.6 μmol/g. Together, these features facilitate highly efficient deoxygenation pathways via decarboxylation (DCO2) and decarbonylation (DCO), while effectively suppressing undesirable cracking side reactions. Furthermore, the catalytic system demonstrated exceptional durability, maintaining a robust yield of 88.5% after three consecutive reaction cycles, illustrating the viability of these Ni- and Ru-based materials for renewable aviation energy solutions.

Abstract

The increasing discharge of organic dyes into aquatic environments requires efficient and sustainable remediation strategies. Although Fe-doped Bi₂O₃ has shown promising photocatalytic performance, the effects of Fe content on its photocatalytic behavior under xenon-lamp irradiation remain insufficiently understood. This study aimed to synthesize different amounts of Fe-doped Bi₂O₃ nanoparticles via a hydrothermal approach and subsequently evaluate their photocatalytic performance toward the degradation of methylene blue (MB). Monoclinic α-Bi2O3 was formed as confirmed by X-ray diffraction analysis, without any detectable secondary phases, suggesting that Fe species were either incorporated into the Bi2O3 lattice or well dispersed in the matrix. Furthermore, the band gap energy decreased from 2.92 eV to 2.66 eV as determined by diffuse reflectance spectroscopy combined with Tauc analysis. Photoluminescence analysis revealed a decrease in emission intensity, indicating suppressed electron-hole recombination and enhanced photogenerated charge separation. Among the prepared samples, the sample with 10 wt% Fe-doped Bi₂O₃ exhibited the highest photocatalytic activity with about 99% degradation of 10 ppm MB within 14 min at optimum experimental conditions (pH of 8, 45 °C). The degradation followed a pseudo-first-order kinetic model with a rate constant of 0.134 min−1. The improved photocatalytic efficiency is attributed to Fe-induced band-gap narrowing and enhanced charge separation, highlighting its potential for wastewater treatment applications.

Abstract

1,2,3-Triazole is an aromatic, five-membered, π-excessive heterocycle comprised of three regular nitrogen atoms. 1,2,3-Triazoles possess a broad spectrum of bioactivities such as anticancer, antimicrobial, anti-inflammatory, antidiabetic, antiviral, and anti-HIV activity. Several compounds containing 1,2,3-triazole-moiety have been employed as drugs in the market. In organic synthesis, these heterocycles also play an important role as building blocks for different transformations. Furthermore, applications of 1,2,3-triazole derivatives as agrochemicals, corrosion retardants, polymers, optical brighteners, photostabilizers, pigments and metal chelators have also been well reported. Due to a wide range of applications, the synthesis of 1,2,3-triazoles has attracted tremendous research interest of chemists and a huge number of studies on the synthesis of these heterocycles have been published over the years. In this review article, we focus on the use of nanocatalysts for the synthesis of 1,2,3-triazoles. 70 studies on the synthesis of 1,2,3-triazoles using nanocatalyst from 2014 have been collected and analyzed. We also try to describe reaction mechanisms as much as we can. The study might be useful for chemists who work in heterocyclic synthesis or medicinal chemistry.

Abstract

The demand for high-quality fuel with a high-octane number or Research Octane Number (RON) continues to increase due to strict emission standards and the ban on lead-based additives. This study aims to develop a catalyst material based on Indonesian natural zeolites from Lampung (ZAL), Bayah (ZAB), and Tasikmalaya (ZAT) through pre-treatment optimization to obtain comparable mesoporous material properties with Mobil Composition of Matter No. 41 (MCM-41). This catalyst is designed for the isomerization process of n-hexane into iso-hexane as a model compound for light naphtha. The research focuses on utilizing Indonesian natural zeolite in combination with desilication techniques using NaOH and cetyltrimethylammonium bromide (CTAB) as surface directing agents. The catalyst is characterized by using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), Surface Area Analysis (SAA), and Scanning Electron Microscopy (SEM) to identify the surface morphology of zeolite. XRD results show structural alteration in the low-to-high θ/2θ region with increasing NaOH concentration. XRF analysis reveals that the bulk Si and Al contents remain relatively stable (Si: 34.73-36.6 wt%; Al: 6.55-8.1 wt%), confirming that desilication occurs selectively at the crystal surface rather than altering the bulk composition. SAA data demonstrate substantial enhancement of textural properties, with the specific surface area increasing from 40.5 to 131.7 m²/g for ZAL, 36.5 to 134.9 m²/g for ZAT, and 46.9 to 101.0 m²/g for ZAB after 1.5 M NaOH treatment. SEM images reveal morphological changes from a defined crystalline texture to a more dispersed surface upon increasing NaOH concentration.

Abstract

Photoelectrocatalytic (PEC) water splitting utilizing titanium dioxide (TiO2) photoanodes presents a promising avenue for sustainable hydrogen production. Understanding the correlation linking the synthesis conditions to structural and phase evolution of semiconductor materials, which is essential for the development of photoanodes with improved PEC activity, remains challenging. This study aims to elucidate the structure- and phase-dependent PEC activity of TiO2 nanoparticles (NPs) obtained via the non-isothermal decomposition of titanium oxyacetylacetonate (TiO(acac)₂) precursor at varying final temperatures (Tfin). The microstructural parameters and phase composition of the TiO2 NPs were determined via Rietveld refinement of X-ray diffraction (XRD) data. The PEC activity of spin-coated TiO2/FTO photoanodes was evaluated via open-circuit potential (OCP) measurements, OCP decay, and linear sweep voltammetry (LSV) under chopped illumination. The results indicate that the anatase-rutile ratio and crystallite dimensions can be modulated by varying Tfin in the range of 500-700 °C. An optimized mixed-phase TiO2 comprising 71.7% anatase and 28.3% rutile, with the crystallite sizes Dav of 29.6 nm and 55.6 nm, respectively, is achieved at 650 °C enabling an efficient transition to free-electron transport and maximized photoactivity. These findings offer essential design principles for managing structural and phase transformations in TiO2-based photoanodes via the metal-organic decomposition route.
