Summary: This study explores the catalytic activity and reaction pathway of oxygen functionalized hexagonal boron nitride (h-BN) in the oxidative dehydrogenation (ODH) of light alkanes. It is found that the synergy of >B-O-O-B< and >B-O-B< active sites at the zigzag edges of h-BN is crucial for the reaction. The ODH reaction temperature decreases with the increase in molecular mass of the light alkanes. The charge redistribution and localized oxygen atomic states during H-transfers provide possible descriptors for the design of new catalysts.

Summary: The article explores the importance of mass transfer in catalytic processes, specifically in the electrocatalytic oxygen reduction reaction (ORR) by tailoring the pore sizes. By employing a confined-etching strategy, boron-and nitrogen-doped carbon (B,N@C) electrocatalysts with abundant active sites but different porous structures were fabricated. The ORR performance was found to be correlated with reactant diffusion, with the optimized B,N@C catalysts featuring trimodal-porous structures demonstrating enhanced O2 diffusion and improved activity per heteroatomic site. The study highlights the significance of nanoarchitecture engineering in catalysts and provides insights into optimizing structures with abundant active sites and enhanced mass transfer.

Summary: In this study, a controllable synthesis of heterophase molybdenum carbides (MoC/Mo2C) using a simple ball milling method without external thermal input was reported. The obtained MoC/Mo2C catalysts exhibited excellent HER electrocatalytic activity and durability at all pH conditions compared to MoC or Mo2C alone. The in situ formed interface of MoC/Mo2C was identified as the key factor in improving the electrocatalytic activity. This fabrication method is cheap and effective in generating heterophase interfaces, which can be employed in many other fields where interface engineering is needed.

Summary: High thermal stability and sluggish absorption/desorption kinetics are limitations for using MgH2 as a hydrogen storage medium. Introducing a suitable catalyst, such as the novel nanoparticulate ZrNi, can significantly improve the hydrogen storage properties. The catalytic reaction of nano-ZrNi during the first de-/hydrogenation cycle forms active species that enhance the breaking and rebonding of H-H bonds and provide multiple hydrogen diffusion channels, leading to remarkably improved hydrogen absorption and desorption capabilities.

Summary: High operating temperatures and sluggish kinetics are obstacles for the practical application of MgH2 as a solid hydrogen carrier. This study investigates the catalytic activity of nanostructured niobium oxide (Nb2O5) and explores the relationship between nanoparticle size, morphology, and catalytic activity. The results demonstrate that the primary particle size is the decisive factor in the catalytic activity of Nb2O5, enabling dehydrogenation at low temperatures and higher reactivity due to the formation of more uniform and finer Nb-based active species when ball-milled with MgH2.

Summary: This research investigated the decomposition of perfluorooctanoic acid (PFOA) using immobilized ZnO nanoparticles through electrophoretic deposition in photocatalysis and photoelectrocatalysis. ZnO nanoparticles show high potential for PFOA degradation due to their process performance, application under visible light exposure, and cost-effectiveness. The study found that the addition of peroxymonosulfate (PMS) could enhance PFOA photocatalytic decomposition over ZnO films, and both UV irradiation and visible light exposure were effective in initiating PFOA degradation. The research also demonstrated the excellent degradation performance of ZnO in photoelectrocatalysis, despite the potential ZnO corrosion caused by PMS.
