Phytate-Coordination Triggered Enrichment of Surface NiOOH Species on Nickel Foam for Efficient Urea Electrooxidation
文献摘要：
Nickel(Ni)-based materials are promising electrocatalysts for the urea electrooxidation reaction,as the in situ formed NiOOH species on their surface during operation are catalytically active sites.In this work,phytate-coordinated Ni foam(PA-NF)is shown to deliver a high catalytic performance,with a potential as low as 1.38 V at 10 mA/cm2,a Tafel slope as low as 64.1 mV/dec,and superior catalytic stability.Char-acterizations revealed that such a high performance was ascribed to the kinetic ac-celeration of surface reconstruction and the enriched NiOOH active species on the PA-NF surface owing to PA-coordination induced upshift of d-band center of Ni sites.Overall,a novel and simple strategy is provided for designing the efficient as well as universal Ni-based catalyst for the electrooxidation of urea,which can also be ex-tended to other transition-metal-based systems.
