Summary: Shape-specific CeO2 nanocrystals (spheres, rods, cubes and nanoparticles) were synthesized and used as support for Ni/CeO2 catalysts for glycerol steam reforming. The morphology of the CeO2 support affected the metal-support interaction and the specific surface area of nickel and oxygen vacancy concentration, thereby influencing the catalytic performance. Ni/CeO2-S with mainly exposed (111) type planes showed the strongest metal-support interaction, resulting in high glycerol conversion and hydrogen production. In contrast, Ni/CeO2-NR and Ni/CeO2-NC with lower exposure areas and oxygen vacancy concentrations showed poorer catalytic activity. The study of the Ni-CeO2 interaction can provide valuable insights for designing efficient GSR catalysts.

Summary: The global demand for alternative renewable energy sources is increasing due to the consumption of fossil fuels and the increase in greenhouse gas emissions. Hydrogen (H-2) from biomass gasification is a green energy segment among the alternative options. Researchers use computational fluid dynamics (CFD) models to study the performance of reforming and membrane reactors for hydrogen production, as well as the effect of operating parameters on the methane stream, improving the process for reforming untreated biogas.

Summary: In this study, LDHs-derived Ni-Al nanosheet arrays (NiAl/NA) were synthesized via a one-step hydrothermal method and used in the steam-reforming of glycerol reaction for enhanced and stable hydrogen production. The catalysts were characterized using various techniques, and the results showed that smooth and cross-linked Ni-Al mixed metal oxide nanosheets grew on the Ni foam substrate. The NiAl/NA catalyst exhibited improved glycerol conversion, higher H-2 yield, and longer stability compared to traditional Ni-Al nanosheet powder, mainly due to its array structures providing improved reducibility and more exposed active sites.

Summary: The study investigated a 2D ZnV2O6 heterojunction modified by reduced graphene oxide and g-C3N4 for enhanced photocatalytic CO2 reduction under visible light. The composite catalyst showed excellent photoactivity, with a maximum CO yield rate 7.4 and 1.7 times higher than using g-C3N4 and ZnV2O6 alone, respectively. The improvements were attributed to the synergistic effect of the 2D layer heterojunction and enhanced charge separation by the RGO mediator under visible light.
