TiO2纳米管内限域纳米Ru及其光催化降解罗丹明B的性能研究
Nano-Ru confinement inside TiO2 nanotube with highly efficient visible light photocatalytic performance
摘要
Abstract
The exterior surfaces of the TiO2 nanotube (TNT)were modified by a silane coupling agent to make nano-Ru selectively deposit on the inner wall.The as prepared catalysts were characterized by transmission electron microscope (TEM),high-resolution transmission electron microscopy (HREM), energy dispersive spectrometer (EDS),high-angle annular dark field image (HAADF),scanning trans-mission electron microscopy (STEM)and UV-vis absorption spectra.The results confirm that nano-Ru particles in the range of 2 ~3 nm in diameter are entrapped in the TNTs.TNTs-confined 2% Ru exhibits the best photocatalytic performance,which photocatalytic efficient is 1 .8 times of pure TNTs.关键词
