Polymorphic cobalt diselenide as extremely stable electrocatalyst in acidic media via a phase-mixing strategy
Noble-metal-free catalysts often show stability issues in acidic media due to structural degradation. Here authors show that phase-mixed engineering of cobalt diselenide electrocatalysts can enable greater covalency of Co-Se bonds and improve robustness for catalyzing hydrogen evolution in acid.
