FeCo-TA@CMS对氧还原反应的催化研究

FeCo-TA@CMS Study on Catalysis of Oxygen Reduction Reaction

氧还原反应在能源转换过程中至关重要,但其反应动力学迟缓,需要高效的电催化剂加速反应进行。本实验以三聚氰胺海绵为碳基底,单宁酸为螯合剂,六水合氯化钴及六水合氯化铁为过渡金属源,合成了铁钴合金掺杂的碳材料(FeCo-TA@CMS),并研究了其电催化性能,发现FeCo-TA@CMS的半波电位高达0.83 V,且极限电流密度接近商业铂碳。

Oxygen reduction reaction is very important in the process of energy conversion,but its reaction kinetics is sluggish,which requires an efficient electrocatalyst to accelerate the reaction.In this experiment,a melamine sponge was used as the carbon substrate,tannic acid was used as the chelating agent,cobalt chloride hexahydrate and ferric chloride hexahydrate were used as the transition metal source.A carbon material doped with iron-cobalt alloy(FeCo-TA@CMS)was fabricated.The electrocatalytic performance of FeCo-TA@CMS was found to have a half-wave potential as high as 0.83 V and a limit current density close to that of commercial platinum carbon.
