Edge-Vacancy Synergy in Cracked Janus WSeS Monolayers for Efficient Hydrogen Evolution.
The catalytic performance of two-dimensional (2D) transition metal dichalcogenides (TMDs) for the hydrogen evolution reaction (HER) is severely limited by the scarcity of active edge sites and intrinsically inert basal planes. Although Janus TMDs mitigates this issue by activating the basal plane through an inherent ve...
