Beyond Carbon: The Structural and Functional Spectrum of Boron Nitride Nanotubes

Abstract

Traditional Boron Nitride (BN) material is a resistant refractory compound of boron and nitrogen with various crystalline forms. BN is electronic to carbon and, thus in the same way carbon exists as graphite in the hexagonal phase. The hexagonal form that corresponds to graphite is used as a lubricant and an add-on to cosmetic products because of its higher stability and limpness. Even through physical and chemical modification, h-BN shows tuneful properties that make it interesting for energy conversion and storage devices. The excellent stability and environment-friendly nature make h-BN-derived materials, particularly for green energy applications. Various predominant technologies are available to satisfy zero emissions of CO2 but still face many challenges such as poor safety, limited cycle life, low efficiency, etc. The h-BN is attractive due to its mechanical strength, chemical inertness, and extraordinary thermal stability which have appeared to meet some challenges of energy storage devices. This review provided an overview of functional properties, their energy-related applications, and future challenges and advancement of BN materials.
