A facile approach has been developed to prepare B,N co‐doped graphene with tuneable composition simply by thermal annealing graphene oxide in the presence of boric acid and ammonia. The resultant BCN graphene (see picture; C gray, H white, B pink, N blue) has superior electrocatalytic activity over commercial Pt/C electrocatalysts for the oxygen reduction reaction in alkaline media.
