Super-stable SnO₂/MoS₂ enhanced the electrocatalytic hydrogen evolution in acidic environments.

ABSTRACT: For electrocatalytic hydrogen evolution in acidic environments, the stability of catalysts has always been a significant factor restricting development. Here, we prepared a superstable SnO₂/MoS₂ coupled nanosheet array on carbon cloth (CC@SnO₂/MoS₂), exhibiting an overpotential of 166 mV at a current density of 10 mA cm^-2. According to the results of various tests and theoretical calculations, it is shown that the establishment of SnO₂/MoS₂ interface engineering is to accelerate the electron transmission on the heterogeneous interface and S defects on the edge of MoS₂, and finally improve the conductivity and catalytic activity of the catalyst. More importantly, the formation of an SnO₂ inter
