摘　　要：以金属有机骨架(MOFs)为模板,通过简单的阳离子掺杂方法合成了Fe/Co-MOFs前驱体,然后进行磷化得到其磷化物(Fe-Co-P),并对其磷化物进行HER性能研究。利用XRD、SEM、TEM、BET和电化学测试等技术对所得催化剂的组分结构和电催化性能进行了表征和测试。结果表明:Fe-Co-P由于具有多孔性和大的比表面积等优势,其电催化HER性能明显高于CoP电催化剂材料。在酸性电解质中,Fe-Co-P达到10 mA·cm^(-2)的电流密度所需过电位为399.4 mV,且Fe-Co-P拥有良好的稳定性和耐久性。本研究可为构建非贵金属基电催化剂在能源领域的应用提供新的指导。The precursor of Fe/Co-MOFs was synthesized by a simple cation-doping strategy using metal-organic frameworks(MOFs) as template. Then, the phosphide(Fe-Co-P) was obtained by phosphating reaction, and the HER properties of the catalyst was studied. Moreover, the composition, structure and catalytic performance of the catalyst were tested through the characterization and testing techniques as XRD, SEM, TEM, HRTEM, BET and electrochemical measurements. The results showed that the HER performance of Fe-Co-P was significantly higher than CoP because of the advantages of the porosity and large specific surface area. In acidic electrolyte, the overpotential required for Fe-Co-P to reach the current density of 10 mA·cm^(-2)was 399.4 mV, and Fe-Co-P had good stability and durability. This study can provide new guidance for the construction of non-precious metal-based electrocatalysts in the field of energy.
