• Nitrogen doped TiO2
• Porous boron nitride
• Visible light absorption
• RhB degradation

A novel TiO2-xNx/BN composite photocatalyst was prepared via a facile method using melamine-boron acid adducts (M.2B) and tetrabutyl titanate as reactants. The morphological results confirmed that nitrogen-doped TiO2 nanoparticles were uniformly coated on the surface of porous BN fibers. A red shift of absorption edge from 400 nm (pure TiO2) to 520 nm (TiO2-xNx/BN composites) was observed in their UV-Vis light absorption spectra. The TiO2-XNx/BN photocatalysts exhibited enhanced photocatalytic activity for the degradation of Rhodamine B (RhB) and the highest photocatalytic degradation efficiency reached 97.8% under visible light irradiation for 40 min. The mechanism of enhanced photocatalytic activity was finally proposed.
