摘要:

纯纳米二氧化钛禁带较宽,只能在紫外光下激发。拓宽二氧化钛的光谱响应范围,实现可见光激发,是二氧化钛基光催化材料面临的主要问题。氮掺杂二氧化钛具有良好的可见光催化活性,是具有可见光响应的二氧化钛基光催化材料的典型代表,近十年来受到了广泛关注。本文综述氮掺杂二氧化钛可见光响应机理和提高光催化活性方面的研究进展,提出今后值得关注与研究的方向。

The pristine titania nanomaterial can only be excited by ultraviolet light because of its wide band-gap.Extending the optical response to the visible light spectrum is one of the most important aspects to the TiO2-based photocatalyst.Nitrogen-doped titania has high visible light photocatalytic activity,which is representative of TiO2-based photocatalyst with reactivity under visible light,and has received enormous attention from scientists and engineers in the past decade.In the current review,the recent progress in research on the origins of visible light responses and the improvement of photocatalytic activity of nitrogen-doped titania are discussed in detail,and urgent issues for future research and development are proposed.
