Graphene-supported hemin as a highly active biomimetic oxidation catalyst

Angew Chem Int Ed Engl. 2012 Apr 16;51(16):3822-5. doi: 10.1002/anie.201108400. Epub 2012 Feb 24.

Abstract

Well supported: stable hemin-graphene conjugates formed by immobilization of monomeric hemin on graphene, showed excellent catalytic activity, more than 10 times better than that of the recently developed hemin-hydrogel system and 100 times better than that of unsupported hemin. The catalysts also showed excellent binding affinities and catalytic efficiencies approaching that of natural enzymes.
