Review on the Energy Transformation Application of Black Phosphorus and Its Composites

Abstract

Black phosphorus (BP) is a unique two-dimensional material with excellent conductivity, and a widely tunable bandgap. In recent years, its application in the field of energy has attracted extensive attention, in terms of energy storage, due to its high theoretical specific capacity and excellent conductivity, black phosphorus is widely used as electrode material in battery and supercapacitors, while for energy generating, it has been also used as photocatalyst and electrocatalysts to split water and produce hydrogen. Black phosphorus demonstrates even better stability and catalytic performance through further construction, doping, or heterojunction. This review briefly summarizes the latest research progress of black phosphorus and its composites in energy preparation and storage, as well as ammonia nitrogen fixation, and also looks into the possible development directions in the future.
