The development of a highly efficient hybrid catalyst is desirable for the water splitting to produce hydrogen. MoSe2is one of the low-cost candidates; however, its activity for hydrogen evolution reaction (HER) is still not satisfactory due to the low conductivity and poor electrical contact with the charge collection substrate. Herein, we provide a simple approach of synthesizing vertically aligned MoSe2nanoplatelets on the urchin-like HER-active conductive CoSe2nanowire array. Nanostructured MoSe2/CoSe2hybrid catalysts obtained a current density of 10 mA cm−2at overpotentials of only 129 mV, with a small Tafel slope of 38.2 mV dec−1, which is superior to those of most transition metal dichalcogenides (MoSe2, MoSe2–CoSe2hybrids, and so on). The abundant exposed active sites of MoSe2, as well as an efficient electrical contact between MoSe2nanosheets and CoSe2nanowires, which is beneficial for the outstanding HER performance of MoSe2/CoSe2hybrid electrode.
