Abstract

Engineering intrinsic selenium vacancies (Se-vacancies) was achieved in mechanically exfoliated WSe2 monolayer nanosheets (WSe2 MLNSs) via an annealing treatment. Our theoretical and experimental results reveal that these Se-vacancies can efficiently activate and optimize the basal planes of the WSe2 MLNSs. As expected, the optimized catalyst exhibits efficient electrocatalytic hydrogen evolution.
