Theoretical framework reveals how reaction conditions tune catalyst selectivity
Schematic representation of the theoretical framework: Starting with a computational model of the prepared catalyst, scientists use density functional theory calculations and kinetic modeling to map phase changes under different reaction conditions. This approach allows you to discover how reaction conditions affect the active phase of a catalyst and how reaction conditions can be used to influence catalyst performance. Credit:…

Schottky junction catalyst promotes hydrogen production by non-precious metals in water electrolysis
By KeAi Communications Co. The space charge region generated by the dual modulation induced a local “OH and H+ rich” environment, selectively promoting the OER and HER kinetic behaviors. Credit: Guangping Yang, Sining Yun. Electrically driven water electrolysis has attracted attention as an environmentally friendly method for hydrogen production, as high-purity hydrogen is essential to resolving the energy crisis. However,…
