Research on Oxygen Evolution Performance of Ru and Fe Co-doped Co_(2)P under Photodeposition Technology

采用“水热—光沉积—气相磷化”法在泡沫镍(NF)上成功合成了Ru、Fe共掺杂Co_(2)P花簇(Ru,Fe-Co_(2)P/NF)。该催化剂具有优异的OER性能,在0.331 V的过电位下即可获得1 A/cm^(2)的电流密度,比基准RuO2-NF催化剂所需电压低40.5%,因此,Ru,Fe-Co_(2)P/NF具有良好的工业应用前景。实验结果说明利用光沉积技术进行Ru的掺杂,很好地提高了Fe掺杂Co_(2)P的OER性能,为贵金属与过渡金属催化剂的结合提供了一种新手段。

Ru and Fe co doped Co_(2)P clusters(Ru,Fe-CO2P/NF)were successfully synthesized on foam nickel(NF)by"hydrothermal photo deposition vapor phase phosphating"method.This catalyst has excellent OER performance,achieving a current density of 1 A/cm^(2)at an overpotential of 0.331 V,which is 40.5%lower than the required voltage of the benchmark RuO2-NF catalyst.Therefore,Ru,Fe Co_(2)P/NF have good industrial application prospects.The experimental results indicate that the use of photodeposition technology for Ru doping effectively improves the OER performance of Fe doped Co_(2)P,providing a new approach for the combination of precious metals and transition metal catalysts.
