The FeS2/NiS2 and FeP/Ni2P composites have beeen synthesized through a two-step method using Fe(NO3)3?9H2O, Ni(NO3)2?6H2O, sulfur powder or NaH2PO2?H2O as raw materials. The structure and morphology are characterized by using XRD, SEM and TEM, the catalytic performances of the two catalysts for oxygen evolution reaction have been investigated. The results show that the catalysts described above exhibit excellent catalytic performances. The FeP/Ni2P composite show higher catalytic activity with small overpotentials of 300 mV at the current density of 10 mA/cm2 for the OER than FeS2/NiS2 (370 mV). The corresponding Tafel slope of the FeP/Ni2P catalyst (48 mV/dec) are also smaller than FeS2/NiS2 (71 mV/dec), revealing more favorable electrocatalytic kinetics on the FeP/Ni2P catalyst for the OER.
