提出了一种新的双水热法制备硼氮共掺杂TiO2的新方法。合成催化剂有两种不同的方法，一种是先加硼再加氮，另一种是先加氮再加硼。x射线光电子能谱分析表明，先加入氮气后，硼和氮的协同作用在催化剂表面形成Ti−B−N−Ti和Ti−N−B−O化合物。先加入硼时，催化剂表面只存在Ti−N−B−O。以上两种化合物都被认为增强了共掺杂TiO2的光催化活性。密度泛函理论模拟也用于研究B−N的协同效应。对于（101）表面，Ti - B - N - Ti结构的形成在TiO2带隙内产生局域态。
A novel double hydrothermal method to prepare the boron and nitrogen codoped TiO2 is developed. Two different ways have been used for the synthesis of the catalysts, one through the addition of boron followed by nitrogen, and the other through the addition of nitrogen first and then by boron. The X-ray photoelectron spectroscopy analysis indicates the synergistic effect of boron and nitrogen with the formation of Ti−B−N−Ti and Ti−N−B−O compounds on the surface of catalysts when nitrogen is introduced to the materials first. When the boron is added first, only Ti−N−B−O species occurs on the surface of catalysts. The above two compounds are all thought to enhance the photocatalytic activities of codoped TiO2. Density functional theory simulations are also performed to investigate the B−N synergistic effect. For the (101) surface, the formation of Ti−B−N−Ti structures gives rise to the localized states within the TiO2 band gap.
