摘要：
The exploration of multiphases and 0D/2D heterojunction in transition metal phosphides (TMPs) and transition metal sulfides (TMDs) is of major interest for hydrogen evolution reaction (HER). Herein, a novel combination route where 0D mixed-phased 1T/2H molybdenum sulfide quantum dots (MoS2 QDs) are uniformly anchored on the 2D CoPx nanosheets is developed. MoS2 QDs and CoPx were prepared via hydrothermal method and mixed with different ratios (Mo:Co ratios of 2:1, 1:1, and 1:2) and annealed under different temperatures to modulate their application in acidic HER processes. Specifically, 2Mo/1Co exhibited advanced performance for HER in 0.5 M H2SO4 solution and required 14 mV to deliver 10 mA cm(-2) and revealed a descended Tafel slope of 75.42 mV dec(-1) with 240 h stability except obvious deactivation. The successful design and construction of 0D/2D mixed-dimensional materials would broaden the application of MoS2 and CoPx for electrocatalytic hydrogen evolution.
