Two-dimensional Functionalized Hexagonal Boron Nitride (2D h-BN) Nanomaterials for Energy Storage Applications

Abstract

The conservation of energy and the materials utilized for its storage have gathered a wide range of interest nowadays. Two-dimensional hexagonal boron nitride (2D h-BN), often termed as ‘white graphene’, exhibits various interesting properties and hence, acts as a promising future candidate for energy sustainment and storage. This material assures exquisite thermal and chemical stability, high chemical inertness, exotic mechanical strength, and good optoelectrical properties. 2D h-BN undergoes physical and chemical modulations, and their properties could be tuned, making them more appropriate for energy storage applications. They could also be incorporated with other 2D materials like graphene, molybdenum disulphide (MoS2 ), etc., to improve their properties. It is thus thoroughly and systematically studied for its further usage in field effect transistors (FETs), UV detecting devices and emitters, photoelectric and microelectronic devices, tunnelling devices, etc. The comprehensive overview provides an insight into 2D h-BN and its synthesis routes developed within the past years. The different major properties exhibited by 2D h-BN are also reviewed. Hybridization and doping processes are also discussed. Functionalised h-BN and its utilisation in different energy storage applications are elaborated and reviewed. This review chapter will give a quick glance and perspectives on 2D h-BN and its extraordinary characteristic features that could enhance their usage in energy conversion, storage, and utilisation applications.
