Abstract

This study aims to synthesize SiO2 gel-based adsorbents using the sol-gel method from Mount Semeru volcanic ash through varying concentrations of sodium hydroxide and acid catalysts and to determine its adsorption capacity on nickel (Ni(II)). Volcanic ash was obtained from Lumajang District, East Java, Indonesia. The silica gel adsorbent was made using the sol-gel method with different amounts of NaOH (1.0 M, 2.0 M, 3.0 M, and 4.0 M) and acid catalysts (acetic and hydrochloric acid). First, silica (SiO2) was extracted from the volcanic ash, and then the sol-gel process was used to manufacture SiO2 gel-based adsorbents. The SiO2 gel was analyzed using X-ray Fluorescence Analysis, Fourier-transform Infrared (FTIR), and Brunauer Emmett, and Teller (BET). Adsorption analysis of the Ni(II) metal ion content was conducted at various stirring rates and adsorbent dose masses. The results obtained showed that the most optimal SiO2 gel was achieved when using 3.0 M NaOH, 10.53% HCl, and 8.30% CH3COOH. Through FTIR analysis, NaOH 3.0 M x HCl silica contains only the siloxane groups, whereas NaOH 3.0 M x CH3COOH silica contains both the silanol and siloxane groups. The best results were gained with SiO2-based adsorbents (NaOH 3.0 M x CH3COOH) at a dose of 10 g/L and a stirring rate of 50 rpm, with Ni(II) adsorption effectiveness of 99.80%.

Abstract

Fe-N-C is a good candidate as the alternative to the expensive Pt/C catalyst for oxygen reduction reaction (ORR). However, their catalytic activity and durability are still inferior to the Pt/C catalyst. Recently, MXene has emerged as a promising material as the catalyst support for the ORR application due to its good conductivity and mechanical properties. In this work, the MXene-supported Fe-N-C catalyst was synthesized using the one-pot pyrolysis method, in which the MXene was directly added during the preparation of Fe-N-C at various pyrolysis temperatures and mass ratios of Fe salt. The works showed that the one-pot synthesis of Fe-N-C/MXene is ORR active, and has shown improved current density over Fe-N-C with the optimum pyrolysis temperature of 900 °C and mass ratio of 1:1. In addition, the Fe-N-C/MXene also demonstrated superior durability compared to Pt/C.

Abstract

The selective aqueous phase hydrogenolysis of furfuryl alcohol (FFalc) to 1,5-pentanediol (1,5-PeD) using supported bimetallic ruthenium-tin (Ru-Sn) catalysts on various metal oxide supports (e.g., TiO2, ZnO, ZrO2, Nb2O5, g-Al2O3) and its combination were investigated systematically. The catalysts were prepared via coprecipitation-hydrothermal at 150 oC for 24 h, followed by reduction with H2 at 400 oC for 2 h. Supported Ru-Sn on TiO2(A), g-Al2O3, and ZrO2 catalysts exhibited higher yield of 1,5-PeD (55-69%) than that other catalysts at 180 oC, H2 10-30 bar for 3-5 h. However, those supported catalysts showed poor recyclability after the first reaction run, and therefore further examination on g-Al2O3 supported Ru-Sn was performed. The Ru-Sn catalyst supported on g-Al2O3-metal oxide composites (metal oxides: ZrO2, TiO2(A), TiO2(R), ZnO, Nb2O5, and C) afforded higher FFalc conversion and yield of 1,5-PeD than that of unmodified g-Al2O3 at 180 oC, H2 30 bar for 3 h. Among them, the Ru-Sn/g-Al2O3-TiO2(A) (33%) catalyst could afford the highest yield of 1,5-PeD (80%) at 99% conversion FFalc at 180 oC, H2 10 bar for 5 h. Around 95% of this catalyst can be recycled after the second reaction run and the activity can be restored to initial after reactivation with H2 at 400 oC for 2 h with a 69% yield of 1,5-PeD at 97% FFalc conversion.

Abstract

In order to increase the selectivity for p-ethyltoluene, catalytic systems based on HZSM-5 zeolite modified with orthoboric acid were obtained, which were used in the alkylation of ethylbenzene with methanol. The reaction was carried out in a continuous flow reactor with a fixed catalyst bed in the temperature range of 300-400 °C at atmospheric pressure to study the effect of boron concentration in the composition of HZSM-5 on the selectivity of the formation of ethyltoluenes and p-ethyltoluene. Physicochemical and textural characteristics of the catalysts were characterized by X-ray Diffraction (XRD), Infra Red (IR) spectroscopy, NH3-Temperature Program Desorption (TPD) and low-temperature Nitrogen Adsorption (NA). It was found that the decrease in the density of strong acid sites, reduction in the volume of micropores and increase in the mesoporosity of zeolite as a result of modification are the main reasons for the enhancement of the catalyst selectivity to p-ethyltoluene. Catalyst 5 %B-HZSM-5 in the temperature range of 300 - 350 °C with conversion of ethylbenzene equal to 14.7-18.4 % shows a sufficiently high selectivity for p-ethyltoluene (60.5-70.2 %).

Abstract

In this study, polyesters synthesized from AB Tung oil-based polyols (TOBPs) monomers via step-growth polymerization reactions. TOBPs are polyols made from Tung oil through a series of hydroxylation and epoxidation procedures. They have hydroxyl (OH) and carboxylic (COOH) functional groups. The polymerization was performed in a three-necked round-bottomed flask (250 mL) equipped with a magnetic stirrer, thermometer, and condenser. It is placed in an oil bath to maintain the reaction temperature. The generated moisture was collected using a vacuum pump. In the meantime, oxygen is being expelled from the reactor by nitrogen. The temperature and stirring speed were kept constant for 6 hours throughout the operation. According to the experiment, 150°C was the ideal temperature for polyesterification. The reaction rate constant rose by 4.73 to 19.99% with the addition of the p-TSA catalyst. The [COOH] and [OH] models were nearly identical to the experimental results, demonstrating the viability of the proposed kinetic model. According to the calculation's findings, polymerization without a catalyst yielded activation energies (Ea) and collision factors (A) of 27.2215 kJ/mol and 16.2965 g.mmol-1.min-1, respectively. Then, polymerization with catalyst decreased Ea and A values, which were around 26.4681 kJ/mol and 14.6746 g.mmol-1.min-1. Copyright © 2025 by Authors, Published by BCREC Publishing Group.

Abstract

The increasing depletion of fossil fuel reserves and environmental concerns have accelerated the search for sustainable alternatives, leading to the utilization of biodiesel as a renewable energy source. Glycerol, a key byproduct of biodiesel production, has been extensively investigated for conversion into value-added compounds such as lactic acid, acrylic acid, and 1,2-propanediol (1,2-PDO). Copper-based catalysts have gained popularity due to their low cost, high catalytic efficiency, and environmental friendliness. This review examines various copper-based catalytic systems for glycerol conversion through key processes such as hydrogenolysis, oxidation, steam reforming, and dehydration. The work focuses on how Cu-based bimetallic catalysts, such as Cu-Ni, Cu-Co, and Cu-Zn, improve reaction selectivity and conversion rates via synergistic interactions, better metal dispersion, and optimized redox properties. Furthermore, new catalyst manufacturing methods, such as ammonia evaporation, hydrothermal, and ion exchange approaches, have shown improved stability and reusability. The findings show that Cu-based catalysts successfully facilitate high glycerol conversion, with selective pathways favouring the generation of 1,2-PDO, lactic acid, and acrylic acid under optimal circumstances. However, catalyst deactivation caused by sintering and coke formation remains a concern. Future research should concentrate on creating stable, multifunctional catalysts, adding bio-derived support, and improving reaction conditions to increase long-term efficiency and industrial usability. This review emphasizes the potential of Cu-based catalytic systems in promoting glycerol valorisation and achieving a more sustainable chemical industry.

Abstract

This study aims to synthesize and evaluate the photocatalytic performance of a modified mesoporous silica-based composite, Fe₂O₃/SPG₂₀–SO₃H, for methylene blue degradation. The catalyst was prepared via a soft-template method using P123 surfactant and gelatin as dual structure-directing agents. Characterization results confirmed the formation of Fe₂O₃ crystallites with a dominant size of 2.14 nm and crystallinity of 90.85%. FTIR spectra revealed the presence of –COOH, Si–O–Si, Si–OH, and –OH groups, while sulfonate-related bands (–SO₃H, O=S=O) were not observed in XRD patterns, suggesting amorphous or poorly crystalline sulfonic groups. SEM analysis indicated rod-like catalyst morphology. Photocatalytic testing under various temperatures showed that Fe₂O₃/SPG₂₀–SO₃H achieved the highest degradation efficiency at 70 °C, maintaining over 92.14 % efficiency for up to 120 minutes of contact time. Lower temperatures (5 °C and 15 °C) led to reduced and less stable degradation activity. These results indicate that both sulfonation and iron oxide impregnation, combined with optimal operating temperature, significantly enhance the photocatalytic performance of mesoporous silica systems, offering a cost-effective and environmentally friendly solution for dye-contaminated wastewater treatment.

Abstract

This study explores the impact of Ni, Co, Mn, and Ag doping on the optical and photoluminescence properties of ZnSe quantum dots (QDs). Structural analysis confirms successful dopant incorporation, with XRD revealing lattice strain-induced shifts. Optical studies show that Ni²⁺ and Co²⁺ induce blue shifts, while Mn²⁺ and Ag⁺ create redshifted emissions. Photoluminescence analysis demonstrates that Mn²⁺ doping enhances quantum efficiency to 49.52% via the 4T1 → 6A1 transition. Ag+-doped ZnSe exhibits blue-shifted emissions but suffers from defect-related non-radiative losses. CIE color coordinates validate tunable emissions, confirming potential applications in LEDs, displays, and bioimaging. These findings provide insights into dopant-induced band structure modifications, advancing the design of high-performance luminescent materials for optoelectronics.

Abstract

This modeling study aimed to simulate hydrogen production through dielectric barrier discharge (DBD) in an argon-methane mixture at atmospheric pressure. Argon was selected as an additive due to its high ionization potential, which is expected to facilitate methane dissociation and enhance plasma reactivity. A series of simulations were conducted to assess the impact of varying argon concentrations (ranging from 0% to 90%) on hydrogen generation. A one-dimensional fluid model was employed to investigate methane conversion within the DBD reactor. This approach enabled a comprehensive evaluation of the effects of different Ar/CH₄ ratios, including pure methane, on reactor performance and key plasma characteristics, such as electron density, ion density, and species concentrations. The findings revealed that increasing the argon content significantly enhanced the ionization rate of methane and increased the discharge current, which directly correlated with higher electron density. Moreover, methane conversion efficiency and hydrogen production were found to be strongly dependent on the Ar/CH₄ ratio, with the highest hydrogen yield observed at a 50:50 argon-to-methane mixture.
