Increased nitrogen doping in TiO2(B) with obviously enhanced visible light absorption ability was achieved via a facile pretreatment of HF followed by an annealing process in NH3. The optimized samples showed a 2.8 times photocatalytic hydrogen evolution rate and 4.2 times RhB degradation rate compared with the original TiO2(B).
通过对TiO₂(B)进行简单的氢氟酸预处理，然后在氨气中进行退火处理，实现了TiO₂(B)中氮掺杂量的增加，其可见光吸收能力明显增强。与原始TiO₂(B)相比，优化后的样品光催化析氢速率提高了2.8倍，罗丹明B降解速率提高了4.2倍。
