The design and synthesis of efficient electrocatalysts for hydrogen evolution reaction under all pH conditions is extremely desirable but still remains a challenge. Here a facile method to decorate PdTe nanowires on reduced graphene oxide nanosheets (PdTe NWs/rGO) has been developed. As a robust integrated 2D hydrogen-evolving cathode catalyst, the Pd3.02Te NWs/rGO shows a low onset potential of -7 mV and maintains its catalytic activity for at least 48 h in alkaline media. It requires overpotentials (eta) of 97 and 355 mV to afford current densities of 10 and 100 mA cm(-2), respectively. The Pd3.02Te NWs/rGO also exhibits a high activity and excellent durability in acidic media.
