Sepaktakraw-like catalyst Mn-doped CoP enabling ultrastable electrocatalytic oxygen evolution at 100 mA·cm-2 in alkali media
文献摘要:
Seeking highly active,stable and low-cost electrocatalysts used as both cathode and anode in overall water splitting is very crucial for the sustainable utilization of resources.Herein,a highly efficient and long-term stable oxygen evolution reaction(OER)electrocatalyst Mn-doped CoP on foam Ni(MnCoP/NF)is synthesized by the one-step electrodeposition method.Owing to the syn-ergetic effect among the Sepaktakraw-like morphology,the doped Mn element and the binder-free synthesis method,MnCoP/NF displays superior electrocatalytic activity and electrochemical stability toward OER.MnCoP/NF only requires an overpotential of 266 mV to deliver the current density of 10 mA·cm-2,demonstrating an excellent elec-trocatalytic activity even better than that of commercial catalysts of IrO2/NF.And the retention rate of potential can still be maintained at 99.57%after the durability test as long as 240 h,indicating the prominent electrochemical stability of MnCoP/NF.Simultaneously,MnCoP/NF could be directly used as both cathode and anode in the two-electrode system for overall water splitting,exhibiting a low potential of 1.97 V for reaching 100 mA·cm-2.Impressive long-term stability of MnCoP/NF is also observed by limited activity decay after 240-h durability tests at 10 and 100 mA·cm-2.Thus,this study illustrates a feasible approach to the rational design of highly active and stable electrocatalyst and also provides valuable insights on the improved electrocatalytic performance of water split-ting by Mn doping.
