磷化铁是一种高效析氢和析氧催化剂，为了提高其催化性能，制备了具有多孔结构和均一形貌的FeP，并对其进行了电催化性能分析。分别在酸性和碱性溶液中考察了该催化剂的析氢催化性能，结果表明，该催化剂在碱性测试环境中的催化活性优于酸性条件下的催化活性。另外，在碱性测试环境中，FeP催化剂也表现出很好的析氧催化性能，当电流密度达到10 mA/cm²时，需要的过电位为380 mV，并且具有较小塔菲尔值，约为73 mV/dec。此外，该催化剂还表现出很好的催化稳定性。

Iron phosphide (FeP) shows an efficient catalytic property for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER).In order to improve its catalytic performance,iron phosphide with porous structure and uniform morphology is prepared and evaluated as electro-catalyst for HER and OER.The electrocatalytic performances of the prepared iron phosphide catalyst for HER are investigated in acidic and alkaline solution,respectively.The results indicate that the catalytic activity of the catalyst under alkaline condition is better than that under acidic condition.In addition,the FeP catalyst also shows a remarkable electrocatalytic performance for OER under alkaline condition,with a low overpotential of only 310 mV at a current density of 10 mA·cm^-2 and a small Tafel slope of 73 mV·dec^-1.Moreover,this catalyst also exhibits a good long-term stability.
