Here, we demonstrate the synthesis of sheet-shaped Co2P grown on carbon cloth (sheet-shaped Co2P-CC) through a facile route. Electrochemical measurements indicated that sheet-shaped Co2P-CC with a loading of 0.6 mg cm−2 Co2P (denoted Co2P-CC-0.6) exhibits exceptional electrocatalytic activity in the hydrogen evolution reaction (HER), with an overpotential of 94 mV at a current density of 10 mA cm−2 and a small Tafel slope of 80 mV decade−1 in 1 M KOH. Similarly, sheet-shaped Co2P-CC-0.6 was also found to be an excellent electrocatalyst for the HER in 0.5 M H2SO4 and in 0.5 M phosphate buffer solution (PBS), with overpotentials of 95 and 231 mV at a current density of 10 mA cm−2, respectively. Sheet-shaped Co2P has a large surface area, meaning that it can provide a relatively large number of active sites on its surface, and CC is an highly conductive substrate that, when used in conjunction with Co2P, can enhance the conductivity of the electrocatalyst. These outstanding results show that sheet-shaped Co2P-CC could be an excellent candidate for a highly efficient electrocatalyst.
