2D biphenylene: exciting properties, synthesis & applications.

Abstract

In the current era of nanotechnology, the isolation of graphene has acted as a catalyst for the study and creation of many innovative two-dimensional (2D) materials with distinctive functions. The recent synthesis of biphenylene (BPN), a porous 2D carbon allotrope, has ignited significant research interest due to its unique and tunable properties, making it a promising candidate for diverse applications in hydrogen storage, batteries, sensing, electrocatalysis, and beyond. Although a considerable amount of research has been carried out on BPN, there is hardly any review article on this fascinating material. Therefore, this comprehensive review article focuses on the fascinating properties of the advanced graphene family and 2D BPN. Additionally, there has been an in-depth discussion on 2D BPN, covering its synthesis process, recent advancements, and its applications in various fields. Moreover, this review will be useful to professionals and researchers in materials science, physics, chemistry, chemical engineering, and related subjects since it provides detailed information on the characteristics, synthesis, and applications of 2D BPN.
