摘要：

A hybrid of many few-layer graphene carbon-coated Fe nano particles was produced by pyrolysis of iron tetrapyridinoporphyrazine. It shows high electrochemical activity for oxygen reduction, and exhibits high saturation magnetization and a negligible magnetic hysteresis, suitable for magnetic catalysts and catalyst-support particles.
