“…Hexagonal boron nitride (h-BN), with a two dimensional (2D) graphite-like structure, has opened up a new frontier in materials for the development of clean and renewable energy conversion and energy storage systems on account of high chemical stability, high thermal stability, low density, biocompatibility and environmental friendliness [8,9]. To our knowledge, h-BN is commonly excluded in photocatalysis and photovoltaic conversion applications due to its wide gap [10].…”
