Graphene-based materials show excellent properties in various applications because of their electrical properties, large surface areas, and high tolerance for chemical modification. The use of wet-process is a promising way for their mass production. Heteroatom doping is one of the common methods to improve their electrical, physical, and electrochemical properties. In this work, we develop a new route for the production B-doped graphene-based materials using low-temperature wet-process, which is the reaction between graphene oxide suspensions and a BH3 adduct in tetrahydrofuran under reflux. Elemental mapping images show well-dispersed B atoms along the materials. Various spectroscopic characterizations confirm the reduction of the graphene oxide and incorporation of B atoms into the carbon network as high as ~ 2 at%. The materials showed electrocatalytic activity for oxygen reduction reactions.
