Engineering out-of-plane microstructure enables higher hydrogen production

Abstract

In this issue of Chem Catalysis, Xiong et al. describe the preparation of a strain-controlled MoS₂ monolayer using bubbles toward the electrocatalytic hydrogen evolution reaction (HER). The induced microstructure and intrinsic S vacancies affected the electronic structure, exciton dynamics, and hydrogen adsorption, resulting in larger bubbles. The derived samples exhibited better acidic HER performance.
