Mo Doping Induced Ni Surface Enrichment of Porous Spherical Core–Shell Bifunctional Electrocatalyst for Overall Water Splitting (Small 6/2025)

Water Splitting In article number 2407907, Yinshi Li and co-workers construct a spherical catalyst with a porous core-shell structure via Mo-induced Ni surface polarization strategy to generate hydrogen and oxygen. The surface enrichment of active sites and the process enhancement of mass transport that are attributed to the unique structure enable efficient HER/OER bifunctional catalysis in water electrolysis.
