Biosynthesis approach to nitrogen doped graphene by denitrifying bacteria CFMI-1

Abstract

Here we present a novel approach to prepare N-doped graphene under ambient conditions by denitrifying bacteria CFMI-1. The N element can be effectively introduced into graphene and 8.2% (atom %) N doping level can be achieved. N-doped graphene possesses a size around 300–600 nm and an average thickness of 1–2 nm.
