摘　　要：Transition metal sulfides(TMSs)have been recognized as potential electrocatalysts for hydrogen evolution reaction(HER),where the edges and defects of TMSs are known as the active sites[1-2].MoS2 with layered crystal structure is so far the most frequently investigated one,however,the associated HER activi-ty is restricted by its low conductivity because of the wide bandgap(1.73 eV)[3-4].Although constructing heterostructures,for example,MoS2@CoS2,presents higher HER activity,the synthetic methods are generally limited by either high-pressure hydrothermal or high-temperature annealing procedures,which lead to unsatisfactory electrochemical performance and low pro-ductivity[5-6].
