【摘要】 应用高频等离子体化学气相淀积法 (RF -PCVD) ,以TiCl4+O2 为体系 ,制备出了纳米级的TiO2 粉体 ,通过控制载气的流量得到了不同粒径的粉体 ,并通过X射线衍射可知产物为金红石型和锐钛型的混晶体 ,通过对含苯酚 5 0mg/L溶液的降解实验 ,比较了其与德国产TiO2 粉体的光催化效率更多还原

【Abstract】 In this paper, the technical conditions of preparing TiO 2 nano-particles used as photo-catalyst by Radio Frequency Plasma Chemical Vapor Deposition (RF-PCVD) is studied. And with the existent equipment prepare TiO 2 particle taking on varies size by controlling the flow velocity of Ar as loading gaseity in the system of TiCl 4+O 2. By XRD characterizing we know the particle prepared is the mix type of rutile and anatase.更多还原
