One-pot hybrid physical-chemical vapor deposition for formation of carbonaceous thin film with catalytic activity for oxygen reduction

摘要

A carbonaceous thin film containing Fe and N was formed on a basal plane of highly oriented pyrolytic graphite (HOPG) from iron phthalocyanine (FePc). Hybrid physical-chemical vapor deposition (HPCVD) in a single vessel through a simple heat treatment at atmospheric pressure enabled the formation and was found to be a facile and versatile method. The catalytic activity of the thin film for O_2 reduction was as high as dispersed Pt on a flat glassy carbon (GC) surface in an acidic electrolyte, implying high potential of the carbonaceous materials as well as the formation method.
