Summary: "Inorganic arsenic is a significant threat to human health in industrial wastewater. Sulfite was used to enhance the photocatalytic oxidation of As(III), with pH-dependent mechanisms proposed for radical activation. The presence of Fe(IV) on the catalyst surface, rather than in solution, contributes to a longer catalyst lifespan and improved As(III) removal."

Summary: The study found that nitrogen doped hydrochars (NDHCs) synthesized from shrimp waste using one-pot hydrothermal carbonization have large surface areas and porous surfaces. When used as photocatalysts, the removal efficiency of methylene blue (MB) by NDHCs was significantly higher than that of glucose-derived hydrochar (GHC), attributed to enhanced adsorption by porous surfaces and nitrogen-based functional groups.

Summary: Environmental pollution caused by industries and human activities is a serious global challenge, while the world is also facing an energy crisis due to population growth. Designing solar-driven photocatalysts inspired by plant photosynthesis offers a fantastic solution to use solar energy for environmental pollutant removal. The use of polymeric and non-polymeric-based electrospun composite nanofibers as innovative photocatalysts not only increases photocatalytic activity, but also overcomes the limitations of traditional nanosized powder photocatalysts. These composite nanofibers have shown long-term stability, high photocatalytic efficiency, and suitability for various applications such as water treatment and antibacterial usage.

Summary: Cu-added gamma-Al2O3 catalysts were prepared with varying Cu loadings and the effects of copper oxidation states on catalytic activity were investigated. The results showed that the addition of copper increased the catalyst activity, but excessive copper loading decreased catalytic activity. XRD and TEM analysis indicated the formation of a solid solution of copper oxide species on the surface of gamma-Al2O3. XAS and TPR data demonstrated variations in copper oxidation states among the catalysts.

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.
