Biological reduction of O 2 to H 2 O justifies a serious look at heme as a potential O 2 reduction reaction (ORR) catalyst for low temperature fuel cells. In this study, a novel non-platinum electrocatalyst for ORR was prepared through hemin, which is hydrochloride of heme, supported on Black Pearls...
