Abstract

This article presents a novel synthesis of fluorinated hexagonal boron nitride (F-BN)/Titanium di-oxide (TiO ₂) hybrid nano-composite by sol-gel method. The prepared nano-composite has shown remarkable photo-catalytic activity under visible light illumination. Our results revealed a strong electrostatic coupling between TiO ₂ nanoparticles, while the reduced band gap of F-BN makes F-BN/TiO ₂ highly responsive to visible light. It is also observed that the hybridization of F-BN (with TiO ₂) not only increases the surface absorption but also enhances the electron–hole separation efficiency. The reduced charge carriers’ recombination rate of TiO ₂ nanoparticles leads to visible light driven photo-catalytic activity. Furthermore, the proposed nanocomposite display an excellent cycling stability for up to 5 cycles. Our results would motivate the applications of F-BN/metal oxide nanostructures in multidisciplinary fields especially in water splitting and photo-catalysis.
