Boron-doped graphene powder (CAS number 7782-42-5) is a multi-layered graphene doped with boron atoms. Boron, one of the important doping elements, can induce electron deficiency in graphene with a p-doping effect, while retaining its original sp2 hybridization and conjugated planar structure. As the electronegativity of boron is smaller than that of carbon, the doping of boron to graphene can lead to a clear differentiation of electron densities on the carbon ring structure.

With a much improved electrocatalytic activity, boron-doped graphene exhibits superior oxygen reduction reaction (ORR) catalytic performance. The electron deficient boron atoms can introduce positive charges to the graphene thus enhancing the adsorption of oxygen and promoting O–O cleavage during ORR. Being relatively positively charged, boron-doped graphene can also improve the adsorption of nitrogen to the surface to form B-N bonds for the reduction of nitrogen to ammonia. With a doping level of 6.2%, boron-doped graphene gained an ammonia production rate of 9.8 μg·hr-1·cm-2 and an excellent faradic efficiency of 10.8% at -0.5 V versus reversible hydrogen electrode.
