主 题:Oxygen reduction reaction Iron tetra-amino phthalocyanine Fuel cell Electrocatalyst
摘 要:For the sake of accelerating the commercial application of fuel cells, non-noble metal catalysts with high activity and high stability have been widely developed to replace platinum-based catalysts. Here, we report a simple but cost-effective synthetic strategy using iron tetra-amino phthalocyanine(FePC-NH_2)and modified carbon black(HCB) to obtain a novel oxygen reduction electrocatalyst(named as FePCNH_2/HCB-800) with Fe_2O_3 wrapped in nitrogen-doped carbon(N-carbon) as active site. The HCB as template can effectively promotes the formation of Fe_2O_3 active site in the catalysts. Compared to commercial Pt/C catalyst, the Fe PC-NH_2/HCB-800 catalyst exhibits high electrocatalytic activity for oxygen reduction reaction(ORR) with onset potential of 0.98 V and half-wave potential with 0.84 V vs. reversible hydrogen electrode(RHE). Meanwhile, the catalyst also shows excellent circulation stability. We believe that this work provides a platform for ORR and is conducive to the commercialization of fuel cells and metal-air batteries.
