Heat treatment-induced Co3+enrichment in CoFePBA to enhance OER electrocatalytic performance
文献摘要：
Increasing active metal sites is a valid approach to improve the catalytic activity of the catalyst.Co3+is the main active metal site of Co-based catalysts.In this research work,through the partial transforma-tion of CoFePBA(CFP)via low-temperature heat treatment,the effective control of the Co3+/Co2+ratio has been achieved.The partial transformation strategy of low-temperature heat treatment can not only maintain the original framework structure of CFP,but also increase more active sites.The characterization results show that the CFP-200 sample obtained via heat treatment at 200℃for 2 h under N2 atmosphere has the highest Co3+/Co2+ratio.As an oxygen evolution reaction electrocatalyst,CFP-200 shows the best electrocatalytic activity among all samples.In 1.0 mol/L KOH electrolyte,the overpotential is 312 mV at a current density of 10 mA/cm2.Therefore,low-temperature heat treatment provides an effective method for preparing low-cost and high-efficiency electrocatalysts.
