Abstract

In this study, a series of x %CeO2/TiO2 (x= 1, 2, 3, 5 and 10) catalysts were successfully synthesized with Ce(NO3)3.6H2O as precursor via a simple wetness impregnation method. The resulting samples were characterized by XRD, FTIR, surface area and pore volume measurements, Raman spectroscopy, SEM, and UV-Vis -DRS. These catalysts were used for the degradation of the phenol through three types of advanced oxidation processes (AOPs), namely the heterogeneous Fenton process (photocatalyst/H2O2), the photocatalysis process (photocatalyst/UV), and the photo-Fenton process (photocatalyst/UV/H2O2). The 10 ‎%‎ CeO2/TiO2 catalyst showed superior degradation efficiency of 99.05 ‎%‎, when used in the heterogeneous photo-Fenton process. To determine the optimal conditions for phenol degradation, using the heterogeneous photo-Fenton process, the effects of parameters such as photocatalyst dosage, initial pH, phenol concentration, H2O2 volume, and temperature were investigated. The optimal conditions were as follows: 0.1 g of catalyst, 0.6 mM of hydrogen peroxide, a reaction temperature of 25 °C, an initial pH of 8, an initial phenol concentration of 30 ppm, and a reaction time of 240 minutes. The impact of radical scavengers (such as p-benzonquinone, silver nitrate, EDTA-2Na and propan-2-ol) on degradation efficiency was also studied. For all three oxidation processes, phenol photodegradation could be described by the pseudo-first-order kinetics according to the Langmuir-Hinshelwood model. Furthermore, the catalysts could be easily recovered from the reaction solution by centrifugation and reused for five cycles without significant loss of activity.

Abstract

Benzene ethylation in the presence of HZSM-5 zeolites is a promising method for producing ethylbenzene. This study examined the effects of modifying lanthanum and phosphorus as additives to the HZSM-5 catalyst, tested in the temperature range of 300-500 °C, at a benzene to ethanol molar ratio of 2:1 in a hydrogen stream. The influence of promoters on acidity and pore structure was investigated using X-ray Diffraction (XRD), NH3 Temperature Programmed Desorption (NH3-TPD), Scanning Electron Microscope (SEM), Brunauer, Emmett, and Teller (BET), and Barrett-Joyner-Halenda (BJH). Among 4%La samples, 4%P/HZSM-5 demonstrated higher ethylbenzene selectivity and operational stability associated with a decrease in the density of strong acid sites and an increase in zeolite mesoporosity because of modification.

Abstract

Visible-light photocatalysis has emerged as a sustainable tertiary‐treatment option. Within this arena, copper molybdate (CuMoO4) is attractive because of its narrow bandgap enables direct solar harvesting while relying on earth-abundant elements. Yet pristine CuMoO4 suffers from low surface area (< 10 m2/g), rapid electron-hole recombination and Cu2+ photocorrosion, which curb quantum yields and raise secondary-pollution concerns. This mini review critically synthesizes research published between 2019 and 2025 on strategies devised to surmount these limitations. Four major areas are surveyed: (i) morphology engineering that multiplies active-site density and deepens light scattering; (ii) plasmonic or single-atom noble-metal decoration that extends spectral response and accelerates interfacial charge separation via localized surface plasmon resonance; (iii) band-gap and defect modulation through doping or oxygen-vacancy creation, narrowing band gap and introducing long-lived trapping states, and (iv) construction of p-n heterojunctions (e.g., ZnO/CuMoO4, graphitic carbon nitride/copper molybdate (g-C3N4/CuMoO4) that yield order-of-magnitude rate enhancements by spatially separating redox half-reactions. The synthesis approaches, from hydrothermal and co-precipitation to thermal-decomposition and solid-state reactions directly influence crystallinity, morphology and defect chemistry, with optimal hydrothermal conditions (180 oC, 10 h) producing high-purity α-CuMoO4 microspheres and oxygen-vacancy-rich Cu-rich phases delivering up to a 0.5 eV bandgap reduction. Emphasis is placed on correlating structural descriptors with pollutant-mineralization kinetics and on emerging green-synthesis trends. Remaining challenges and research priorities including stability against Cu leaching, scalable fabrication and in-situ mechanistic probes are highlighted to guide future catalyst design.

Abstract

Biofuel production from biomass sources remains a key area of research, aimed at reducing reliance on fossil fuels and promoting environmental sustainability. This study investigates the conversion of used cooking oil (UCO) into biogasoline via catalytic hydrocracking, employing sulfated mesoporous silica dispersed with nickel as the catalyst. Mesoporous silica was synthesized using tetraethyl orthosilicate (TEOS) and NaHCO₃ as the template, followed by a hydrothermal method to introduce sulfate groups and nickel metal. Among the synthesized catalysts, SMS-2 exhibited the highest acidity across varying sulfuric acid concentrations, while 1 Ni/SMS-2 demonstrated superior acidity compared to other nickel loadings. The SiO₂, SMS-2, and 1 Ni/SMS-2 catalysts were evaluated for UCO hydrocracking in a semi-batch double-furnace reactor operated at an optimum temperature of 550 °C for 2 h, with a hydrogen flow rate of 20 mL min⁻¹ under atmospheric pressure. Modifying mesoporous silica with sulfuric acid and nickel significantly enhanced its catalytic performance, with the 1 Ni/SMS-2 catalyst achieving the highest liquid product yield (66.10%) and gasoline fraction (35.47%) at an optimum catalyst-to-feed ratio of 1:100 (w/w). Notably, the resulting biogasoline exhibited a calorific value comparable to commercial gasoline and was free of aromatic hydrocarbons, indicating the potential for cleaner combustion. This study provides valuable insights into the effectiveness of mesoporous silica-based catalysts, highlighting their acid site modulation capabilities for efficiently transforming waste into high-value fuels.

Abstract

The crystal phase-dependence of ruthenium supported on titania (Ru@TiO2) catalysts on the product selectivity in the aqueous phase hydrogenolysis of furfuryl alcohol (FFalc) was investigated. The supported ruthenium nanoparticles (RuNPs) catalysts on TiO2 with different phases, c.a. rutile (R), anatase (A), and brookite (B) were employed. The Ru@TiO2(R) catalysed the hydrogenation-rearrangement reaction of furan ring to afford cyclopentanone/cyclopentanol (CPO/CPL) as the main product. The presence of high surface acidity in Ru@TiO2(R) catalyst promoted the hydrogenation-rearrangement of furan ring leading to CPO/CPL as the main product as indicated by NH3-TPD and pyridine-ATR-IR results. In contrast, the Ru@TiO2(A) catalyst selectively hydrogenolysed the furan ring to produce 1,5-pentanediol (1,5-PeD). This high selectivity of 1,5-PeD over Ru@TiO2(A) catalyst may be affected by the high dispersion of Ru NPs on TiO2 facets as depicted by the high H2-uptake and small particle sizes.
