Preparation of FePcNs@GO composites and boosting oxygen reduction reaction

By increasing the activity and specific properties of the catalyst during oxygen reduction reactions (ORR), we hope to improve fuel cell performance and energy conversion efficiency. Using a single microwave step, the graphene oxide-decorated iron phthalate catalyst (FePcNs@GO) nanocomposites were synthesised. Some analytical techniques were used to validate the morphology and composition of Fe catalyst/graphene (FePcGO) and FePcNs@GO. In an oxygen-saturated environment, we conducted the ORR electrocatalytic studies on the prepared materials. The results demonstrate that when FePcNs@GO is combined with graphene oxide, it exhibits excellent electrochemical properties. In comparison to commercial FePc and 20% Pt/C, the overpotential is significantly lower. Under nitrogen-saturated conditions, the Fe 2+/3+ redox form potential in FePcNs@GO exhibits a more positive behaviour, which favours strong interactions between Fe 2+ and O 2 . In this work, we demonstrate that platinum-free catalysts have potential applications in ORR.
