摘要
A 3D hierarchical Bi-doped CoP nanoflower electrocatalyst has been developed based on a MOF self-sacrifice strategy. 3% Bi/CoP delivers a current density of 10 mA cm-2 at low overpotentials of 122 mV in alkaline electrolyte and 150 mV in acidic electrolyte, respectively. DFT calculations demonstrate that Bi doping can synergistically optimize the binding free energy of H* on the CoP (202) facet and ultimately improve the HER performance.
