火焰化学气相沉积法制备氮掺杂纳米TiO2研究
Research on Nitrogen Doped TiO2 Nano-particles Prepared by Flame Chemical Vapor Deposition
摘要
Abstract
The flame chemical vapor deposition(CVD) method was used to prepare TiO2 nano-particles using ammonia gas as nitrogen source, TiCl4 as the precursor of TiO2, the oxidation of titanium tetrachloride (TiCl4) in propane-air turbulent flame. First, TiCl4 was used as the precursor of TiO2 to prepare TiO2 nano-particles in propane-air turbulent flame. Then, the N-doped TiO2 nano-particles were calcined in the ambience of ammonia under high temperature in tube furnace. The samples prepared by the two methods were investigated by X-ray diffraction, UV-Vis spectrometer, transmission electron microscopy, X-ray photoelectron spectroscopy. The results showed that the N-doped TiO2 nano-particlas directly prepared by CVD method had high absorbance in the range of 400~500 nm and more amount of nitrogen doping under the same flow rate of ammonia.关键词
