Abstract:
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).
