Abstract
1T-phase molybdenum disulfide is supposed to be one of the non-precious metal-based electrocatalysts for the hydrogen evolution reaction with the highest potential. Herein, 1T-MoS(2) nanosheets were anchored on N-doped carbon nanotubes by a simple hydrothermal process with the assistance of urea promotion transition of the 1T phase. Based on the 1T-MoS(2) nanosheets anchored on the N-doped carbon nanotubes structures, 1T-MoS(2) nanosheets can be said to have highly exposed active sites from edges and the basal plane, and the dopant N in carbon nanotubes can promote electron transfer between N-doped carbon nanotubes and 1T-MoS(2) nanosheets. With the synergistic effects of this structure, the excellent 1T-MoS(2)/ N-doped carbon nanotubes catalyst has a small overpotential of 150 mV at 10 mA cm(-2), a relatively low Tafel slope of 63 mV dec(-1), and superior stability. This work proposes a new strategy to design high-performance hydrogen evolution reaction catalysts.
