摘要:Earth-abundant MoS2 is viewed as a promising HER electrocatalyst, but its HER activitiy is still restricted due to the low fraction of edge sites and poor electronic conductivity. In this work, we combined the Co doping and 1T strategies to promote the HER activity of Co-1T/2H MoS2. Our experimental results demonstrated that Co doping could bring more active sites while the 1T phase benificial fast electron transfer. As a consequence, Co-1T/2H MoS2 displayed markedly improved activity, which only required an overpotential of 178 mV to deliever a current density of 10 mA cm−1 in 1.0 M KOH aqueous solution. And our work also provided an effective strategy for improving the catalytic activity towards other two-dimensional (2D) materials.
