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.

通过溶剂热法将TiO ₂纳米薄片锚固在h-BN薄片的表面，构建了一种新型的层状六方氮化硼/二氧化钛（h-BN / TiO ₂）复合光催化剂。可以通过控制薄片h-BN的数量来调节TiO ₂的形态和分散性。得益于独特的异质结构，所得复合材料对罗丹明B（RhB）降解的光催化性能大大提高，其中12 wt％的h-BN / TiO ₂复合材料的降解率比合成TiO高3.5和6.9倍。₂和商用TiO ₂（P25），并且还获得了优异的循环稳定性。此外，第一性原理计算揭示了TiO ₂和h-BN薄片之间的协同催化作用，这被发现是h-BN / TiO ₂复合材料的显着增强的光催化性能的原因。
