摘　　要：Transition metal dichalcogenides,especially MoS_(2),have been examined as promising catalysts for hydrogen evolution reaction(HER).Meanwhile,MoS_(2)with various nanostructures and exposed more active sites has been broadly explored for boosting the HER performances at wide pH range.Here,a synergistic Pt and Te codoping strategy has been used to enhance the catalytic performance(including reducing the overpotential and promoting the HER reaction kinetics)of ultrathin MoS_(2)nanosheets in alkaline and acid electrolytes,which has delivered better than single Pt doping or single Te doping.
