Abstract

The remote hydrogen plasma is able to create abundant S-vacancies on amorphous molybdenum sulfide (a-MoS_x ) as active sites for hydrogen evolution. The results demonstrate that the plasma-treated a-MoS_x exhibits superior performance and higher stability than Pt in a proton exchange membrane based electrolyzers measurement as a proof-of-concept of industrial application.

Keywords: amorphous molybdenum sulfide; hydrogen evolution reaction; hydrogen plasma; photon exchange; transition metal dichalcogenide.
