title: Controllable selenium vacancy engineering in basal planes of mechanically exfoliated WSe2monolayer nanosheets for efficient electrocatalytic hydrogen evolution.
abstract: Engineering intrinsic selenium vacancies (Se-vacancies) was achieved in mechanically exfoliated WSe2monolayer nanosheets (WSe2MLNSs) via an annealing treatment. Our theoretical and experimental results reveal that these Se-vacancies can efficiently activate and optimize the basal planes of the WSe2MLNSs. As expected, the optimized catalyst exhibits efficient electrocatalytic hydrogen evolution.
