可实现可见光催化的N掺杂TiO2薄膜的制备方法
摘要：
一种可实现可见光催化的N掺杂TiO2薄膜的制备方法，包括如下步骤：(a)用N离子源轰击TiO2薄膜；并且(b)使得所述薄膜中N元素的掺杂量提高到21％。本发明的可实现可见光催化的N掺杂TiO2薄膜催化剂，有相对较高的N掺杂量，减小TiO2价带与导带间的禁带宽度；形成的晶相为anatase相TiO2，并且，可直接制备得到纳米晶结构的anatase相TiO2。
摘要（英）：

The invention discloses a preparation method of an N-doped TiO2 film capable of achieving visible light catalysis. The preparation method of the N-doped TiO2 film capable of achieving visible light catalysis comprises the following steps: (a) bombarding the TiO2 film by using an N ion source; and (b) increasing the doping amount of the N element in the film to 21%. An N-doped TiO2 film catalyst capable of achieving visible light catalysis, which is prepared by the N-doped TiO2 film, is relatively high in the doping amount of N; a forbidden bandwidth between a TiO2 valence band and a guide band is reduced; a formed crystal phase is anatase-phase TiO2; anatase-phase TiO2 of a nanocrystal structure can be directly prepared.
