Abstract

Generating more and fresh active sites is challenging for 2D MoS₂. Herein, the old S edges were peeled off and the inner S atoms were disclosed as under-coordinated atoms. This realized more and freshly active sites being exposed that facilitate adsorption of intermediates and lead to dramatic enhancements in its HER activity in both acid and alkaline electrolytes.
