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.
