采用NH3气流对纳米管钛酸（NTA）进行处理，制备了具有高可见光催化活性的N掺杂TiO2，并采用XRD、TEM、ESR和XPS等手段对其进行了表征。ESR结果表明，N掺杂TiO2的可见光催化活性主要来源于N掺杂形成的三重态顺磁物种，三重态顺磁物种浓度越高，可见光催化性能越好。
A novel N-doped TiO2with high visible light photocatalytic activity was obtained by treating nanotube titanic acid (NTA) in NH3flow and investigated by means of XRD, TEM, ESR and XPS. The ESR results revealed that the visible light photocatalytic activity is originated from N-doping into TiO2with the forming of triplet paramagnetic species, the higher triplet paramagnetic species concentration, the better visible light photocatalytic behavior.
