The strategy that combines fast pyrolysis with controllable induction is adopted to form coordination bonds between iron-based active center in iron based precursor and oxygen element in carbonaceous support,therefore the prepared iron-based electrocatalyst obtains an improved performance of in carbon dioxide electroreduction reaction.It is found through X-ray photoelectron spectroscopy(XPS)and other characterization methods that the strategy can induce effectively to form Fe—O bond,further regulates the electronic properties of the iron-based electrocatalyst.Performance test indicates that under the help of the iron-based electrocatalyst modified by oxygen coordination,Faraday efficiency of carbon dioxide to oxygen can maintain at a high level of nearly 100％in a wide potential range of 410 mV(-0.56 V to-0.97 V).
