A new synthesis approach of hierarchical MoS2 nanoflakes toward hydrogen evolution in both acidic and alkaline media.

Abstract

Herein, ultrathin MoS2 flakes were prepared using a synergistic liquid phase precipitation method by applying ultrasound and microwave simultaneously. At 10 mA cm2 of electric current density, the MoS2 electrocatalysts' passing points are 176 mV and 154 mV respectively in acidic and alkaline electrolytes. This research provides a new synthetic method and potential opportunity in the design and preparation of multiple synergistic high-efficiency electrocatalysts.
