采用金属有机框架（MOF） UIO-66为载体，通过溶剂热法、气相沉积法等制备了一种FeP@PC电催化剂。利用X射线衍射、透射电镜、扫描电镜和X射线光电子能谱对催化剂的形貌和物相成分等进行表征。研究了Fe的投料量对催化剂形貌和性能的影响。该催化剂在析氢反应中表现出优异的电催化活性。在0.5 mol/L硫酸中，电流密度为10 mA/cm²时，所需过电势为145 mV，塔菲尔斜率为96 mV/dec。这种优异的催化活性归因于FeP与碳层之间的协同作用。

Using metal organic framework UIO-66 as the substrate,FeP@PC electrocatalyst is prepared by solvothermal method and chemical vapor deposition (CVD) method,and characterized by X-ray diffraction (XRD),transmission electron microscope (TEM),scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS).The effect of the addition amount of Fe on the morphology and properties of FeP@PC catalyst is studied.The results show that FeP@PC exhibits efficient electrocatalytic activity with a low overpotential at 145 mV when the current density is 10 mA·cm^-2 in 0.5 mol·L^-1 sulfuric acid.Tafel slope of FeP@PC is 96 mV·dec^-1.Such an excellent electrocatalytic performance is attributed to the synergistic effect between FeP and carbon layer.
