Preparation and oxygen reduction performance of mesoporous perovskite/g-C3N4
In this paper,the sol gel-hard template method was used to prepare mesoporous perovskite(LFO)precursor,and high-temperature solid phase reaction was used to prepare g-C3N4.LFO and g-C3N4 were then combined in different proportions.The structure and properties of the composites were characterized and tested by XRD,BET,SEM,CV,LSV and EIS.The results showed that LaFeO3-70％g-C3N4(LFO-70％)had an oxygen reduction potential of 0.75 V,a half wave potential of 0.65V,and an initial potential of 0.8V,exhibiting the most excellent catalytic activity for oxygen reduction.
