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.
