Co-Motif-Engineered RuO₂ Nanosheets for Robust and Efficient Acidic Oxygen Evolution.

ABSTRACT: The development of efficient and reliable acidic oxygen evolution reaction (OER) electrocatalysts represents a crucial step in the process of water electrolysis. RuO₂, a benchmark OER catalyst, suffers from limited large-scale applicability due to its tendency toward the less stable lattice oxygen mechanism (LOM). This work reports the synthesis of Co-doped RuO₂ nanosheets with a unique porous morphology composed of interconnected grains via a facile molten salt method. Co doping modulates the grain size, effectively increasing the specific surface area and introducing oxygen vacancies. These oxygen vacancies, coupled with the Co dopants, form Co-O(V) motifs that tune the electronic configuration of Ru. This structural engineering promotes a shift in the OER mechanism
