MoS2-MoP Heterostructured Nanosheets Supported on Polymer-Derived Carbon for Hydrogen Evolution Reaction

Abstract

Electrocatalytic production of hydrogen from water has been considered as a promising and sustainable strategy. In this study, a simple and general strategy is demonstrated for the synthesis of polymer derived hetero atoms doped carbon support MoS2-MoP nanosheets (MoS2-MoP/C) as an efficient hydrogen evolution reaction (HER) catalyst. The unique composite of MoS2-MoP/C exhibit predominantly HER catalytic performance with a smaller Tafel slope of 58 mVdec-1 and overpotentials of 102 mV and 130 mV to deliver current densities of 10 mAcm-2 and 20 mAcm-2, respectively. Moreover, MoS2-MoP/C nanosheets presents superior long-term durability in acid electrolytes and the developed strategy is easily to adapt to large-scale production of efficient electrocatalysts. The excellent HER performance might be attributed to the electronic interactions between P and S, relative-high specific surface area (162 m2 g-1), characteristic nanosheet morphology, and high electrical conductivity, which promoted fast charge transport and superior collection rate.
