Summary: Alpha-MnO2/BiVO4 nanocomposites with different MnO2 contents (0-7 wt%) were successfully synthesized through a simple chemical method. The structure, morphology, and optical properties of the nanocomposites were studied using various analytical techniques. The photocatalytic efficiency of the nanocomposites was evaluated through the degradation of rhodamine B (RhB) and tetracycline (TC) under visible light irradiation (λ >= 420 nm). The 5% MnO2/BiVO4 (MnBV-5) photocatalyst exhibited the highest degradation efficiency and maintained good stability after five testing cycles.

Summary: Low-dimensional Ga2O3 was synthesized through a simple chemical route, allowing for easy tuning of morphology. Different Gallia precursors led to spherical nanoparticles and fractured nanobricks as the end product. Despite their wide bandgap, both samples showed efficient visible-light-induced photocatalytic degradation of toxic organic pollutants due to sensitization of the dyes. The nitrate-salt-originated nanobricks exhibited higher degradation efficiency towards rhodamine B (RhB) compared to the chloride-salt nanospheres, attributed to their electronic band positions and morphological features such as higher specific surface area, porosity, and aspect ratio. This remediation technology can be applied to optimize future catalyst systems for wastewater treatment fabricated via the hydrothermal-synthesis route.

Summary: Compared to UV-driven catalysts, the use of sunlight to design efficient visible light catalysts has been less explored. In this study, Fe3O4@ZnO@ZIF-8 three-component core-shell nanoparticles were prepared and their photocatalytic degradation performance was investigated under visible light using Rhodamine B (RhB) as a model contaminant. It was found that Fe3O4@ZnO@ZIF-8 achieved a significant enhancement in the photo-catalytic degradation efficiency with 98% of RhB degraded within 100 min, and a reaction rate constant of 0.0292 min-1. These findings highlight the importance of precise tailoring of core-shell Fe3O4@ZnO@ZIF-8 for achieving desired degradation efficiency of organic pollutants under visible light.

Summary: The present study focused on synthesizing novel ZnLaxFe2-xO4 catalysts and utilizing them for the photocatalytic degradation of Rhodamine B dye. The results showed that increasing the amount of La3+ dopant can decrease the band gap energy of the catalysts, thereby improving the degradation efficiency. The optimized catalyst ZnLa0.05Fe1.95O4 exhibited the highest degradation efficiency and reaction rate under visible light irradiation, while also showing high recyclability and stability. This study is of great importance for the development of efficient catalysts for the visible light-driven degradation of toxic dyes.

Summary: In this study, NiGa alloy particles supported on CeO2, ZrO2, and ZrO2-CeO2 solid solutions were prepared and characterized. The nature of the support was found to have a significant influence on the catalyst's activity and selectivity, with the crystalline structure of ZrO2 having the greatest impact. Pure ZrO2 showed the highest methanol selectivity and CO2 conversion at high Zr:Ce ratios. In equimolar and Ce-rich conditions, basic sites and oxygen vacancies were found to be the key parameters affecting methanol production.

Summary: 1,6-Hexamethylenediamine was successfully synthesized via the reductive amination of 1,6-hexanediol using a Ru/PRL(x)-Al2O3 catalyst. The highly dispersed and anchored Ru species, formed by 1,10-phenanthroline (PRL), played a crucial role in the catalytic reaction. The formation of new acid-base pairs, electron deficient Ru species, and smaller nanoparticles contributed to the improved catalytic performances of the Ru/PRL-Al2O3 catalyst.

Summary: Efficiently addressing the challenges of photocatalytic CO2 reduction to CH3OH is crucial. This study developed Zn-BTC MOF and its composites with CaIn2S4, achieving highly efficient and robust photocatalytic CO2 reduction to CH3OH under ambient conditions, using H2O2 as the hydrogen source. Among the composites, ZMCIS4 demonstrated excellent performance with a CH3OH evolution of 49100 μmol/g.cat and a quantum efficiency of approximately 78.41%. The enhanced performance was attributed to the production of nascent hydrogen atoms (H center dot) through the photo-splitting of H2O2 on the ZMCIS surface.

Summary: In this study, several silica-alumina catalysts modified with Ag were examined for the dehydration of 1,3-butanediol to 1,3-butadiene. Among them, an amorphous silica-alumina catalyst (SAL-3) modified with Ag showed the highest improvement in catalytic activity and stability when operated in H2 flow. The generation of reversible acid sites was found to be the reason behind the enhanced activity and stability of this Ag/SAL-3 catalyst. The effects of various parameters on the catalytic activity of Ag/SAL-3, such as reaction temperature, contact time, Ag content, and carrier gas, were investigated.
