Enhanced oxygen reduction performance by novel pyridine substituent groups of iron (II) phthalocyanine with graphene composite

A novel iron (II) tetrapyridyloxyphthalocyanine decorated graphene (FeTPPc/Gr) is synthesized through a simple solvothermal method. FeTPPc/Gr catalyst exhibits superior catalytic performance than Pt/C due to increase additional active sites for the ORR in alkaline conditions.286
