基于MOF自我牺牲策略，开发了一种3D分级Bi掺杂CoP纳米花电催化剂。3%Bi/CoP在碱性电解液和酸性电解液中分别提供122 mV和150 mV的低过电位下的电流密度为10 mA cm（-2）。DFT计算表明Bi掺杂可以协同优化H* 在CoP（202）面上的结合自由能，并最终改善HER性能。
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.
