采用等离子体辅助金属有机化学气相沉积法制备了氮掺杂TiO2纳米粒子。氮掺杂浓度为0 ~ 1.61 %。研究了氮离子掺杂对可见光光催化的影响。采用x射线衍射、透射电子显微镜、x射线光电子能谱、近边x射线吸收精细结构等多种分析技术对样品进行分析。以四异丙醇钛为钛前驱体，以射频等离子体分解氨为氮掺杂源。在管式反应器中，在600°C的氩气和O2气流下，将n掺杂TiO2纳米颗粒沉积在不锈钢网上。采用带紫外滤光器的可见光灯对2-氯苯酚（2-CP）进行了光催化活性测试。采用高效液相色谱法测定了光催化氧化2-CP的效率。
Nitrogen-doped TiO2 nanoparticles were synthesized via plasma assisted metal organic chemical vapor deposition. Nitrogen dopant concentration was varied from 0to1.61at.%. The effect of nitrogen ion doping on visible light photocatalysis has been investigated. Samples were analyzed by various analytical techniques such as x-ray diffraction, transmission electron microscopy, x-ray photoelectron spectroscopy, and near-edge x-ray absorption fine structure. Titanium tetraisopropoxide was used as the titanium precursor, while rf-plasma-decomposed ammonia was used as the source for nitrogen doping. The N-doped TiO2 nanoparticles were deposited on stainless steel mesh under a flow of Ar and O2 gases at 600°C in a tube reactor. The photocatalytic activity of the prepared N-doped TiO2 samples was tested by the degradation of 2-chlorophenol (2-CP) in an aqueous solution using a visible lamp equipped with an UV filter. The efficiency of photocatalytic oxidation of 2-CP was measured using high performance liquid chrom...
