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).
