Co‐doping Graphene with B and N Heteroatoms for Application in Energy Conversion and Storage Devices

Graphene, as an important member of the two-dimensional (2D) class of materials, has been used extensively in a large spectrum of applications due to its remarkable properties. In addition to its properties and its easy modulation through intentional doping with boron (B) and nitrogen (N) heteroatoms leads to the production of graphene derivatives that exhibits a comprehensive arsenal of fascinating properties. More importantly, the different electronegativities of boron and nitrogen heteroatoms bestows graphene with a variety of new and/or improved electromagnetic, catalytic, physicochemical, and optical properties. As a result, doped graphene derivatives have been explored in catalysis, biotechnology, sensors, water purification, and used in many other applications. Nonetheless, there is a shortage of data on the use of B/N co-doped graphene nanomaterials in renewable energy conversion and storage technology. Therefore, this article aims to provide an overview on the recent progress and future aspects of several key applications of B/N co-doped graphene nanomaterials in these areas of energy and storage.
