Abstract

A novel layered hexagonal boron nitride/titanium dioxide (h-BN/TiO₂) composite photocatalyst has been constructed by anchoring TiO₂ nanoflakes on the surface of h-BN flakes via a solvothermal method. The morphology and dispersion of TiO₂ can be tuned by controlling the amount of flake h-BN. Benefiting from the unique hetero-structure, the photocatalytic performance of the obtained composite toward rhodamine B (RhB) degradation is greatly enhanced, among which 12 wt% h-BN/TiO₂ composites show 3.5 and 6.9 times higher degradation rate than the synthesized TiO₂ and commercial TiO₂ (P25), respectively, and an excellent cycling stability has also been obtained. Moreover, the first-principles calculation reveals the synergetic catalytic effect between TiO₂ and h-BN flake, which is found to be responsible for the significantly enhanced photocatalytic performance of h-BN/TiO₂ composites.
