Molybdenum phosphide-carbon nanoflowers (MoP-CFs) were prepared by the gas-solidification method, and C₆₀ was modified on the surface of MoP-CFs to form van der Waals heterojunctions by simple ultrasonic self-assembly. It is found that the modification of C₆₀ can effectively reduce the overpotential of electrocatalytic hydrogen evolution. Among all samples, 10% C₆₀-MoP-CFs (10% was the mass fraction of C₆₀) exhibited the best catalytic activity with overpotentials of 158 and 157 mV to achieve a current density of 10 mA·cm^-2 in acidic and alkaline conditions, respectively. Moreover, this sample also showed good stability which could work stably for more than 20 h. The strong electron coupling between C₆₀ and MoP-CFs promotes electron migration from C₆₀ to the surface of MoP-CFs, reduces the charge transport resistance, and accelerates the electrocatalytic hydrogen evolution interface reaction kinetics process.
