Synergistic zinc doping and defect engineering toward MoS2 nanosheet arrays for highly efficient electrocatalytic hydrogen evolution

Abstract

Herein, we have demonstrated synergistic zinc doping and defect engineering toward MoS₂ nanosheet arrays assembled on carbon cloth (CC) by a one-pot hydrothermal approach for the first time, which are employed directly as a cathode for the hydrogen evolution reaction (HER). In our strategy, simultaneously doping sufficient Zn atoms and introducing a defect-rich structure into a MoS₂ nanosheet can synergistically increase active sites. Additionally, the assembly of such nanosheets on CC can achieve lower charge-transfer resistance for the highly efficient HER.
