摘要：

Complicated synthesis procedure and instability of 1T-MoS2 impede its practical application for hydrogen evolution reaction. Here, we propose a new strategy to drive the synthesis of stabilized 1T-MoS2 by Ni doping. Ni doping forms the Ni - S covalent bonds, inducing the slip of S atoms and stabilizing 1T structure. The materials were characterized by transmission electron microscopy, X-ray photoelectron spectroscopy and Raman spectroscopy. Electrochemical tests including linear sweep voltammetry etc. indicate that the 1T/2H-MoS2/8%Ni has an overpotential of 162 mV and a Tafel slope of 80 mV dec(-1) along with a good stability.
