A Review on the Synergistic Features of Hexagonal Boron Nitride (White Graphene) as Adsorbent-Photo Active Nanomaterial

Hexagonal boron nitride, known as white graphene has attracted the water industry as a replacement to both classical bulk and nano-adsorbent. Its structural resemblance to graphene, resistance to corrosion, chemical oxidation, high thermal stability has attracted the focus of the researchers. On top of that its intrinsic material properties such as porosity, surface functional groups, band gap, etc. can be engineered to complement the real-time applications. All the aforementioned strengthened their potential candidature as alternative nano-adsorbent as well as energy material. The distinct characteristics like high selectivity, affinity, and the polar nature are auxiliary benefits for the adsorptive process. Further, the higher thermal stability of the material paves facile and ease regeneration. However, the wider band position limits its attributes as energy materials and was resolved by simple doping with suitable impurities. The authors drafted review, learning the vacuum that consolidates the mechanistic features like the development of nanoarchitecture, porosity, and bandgap engineering of the said material. Hence, the present review unambiguously discusses the role of various governing parameters for the development of novel porous Hexagonal boron nitride, along with characteristics of typical energy materials.
