| description | CoSe2 is a typical transition metal chalcogenide and an hydrogen evolution reaction hydrogen evolution catalyst due to its efficient and inexpensive characteristics. In this work, CoSe2/CNT composite was synthesized through a one-step solvothermal method. Specifically, a current density of 10 mA cm−2 can be achieved under an overpotential of 163 mV, and the Tafel slope is 69.4 mV dec−1. The reasons for these excellent performances are: 1) the abundant catalytic active sites of CoSe2; 2) the high conductivity of CNTs; and 3) the synergistic effect between CoSe2 and CNTs; iv the solar irradiation excites electrons to join the reaction. This work proposes a new way to reasonably design the high-efficiency and low-cost transition metal chalcogenide hydrogen evolution catalysts. |
