TiO2纳米管负载Ag、Au、Pt纳米粒子的微波合成与表征

摘要

TiO2 nanotubes were prepared under normal pressure at a temperature of 120℃. Ag, Au, Pt nanoparticles supported on TiO2 nanotubes were prepared by microwave assisted heating polyol process. TEM images showed that microwave prepared Ag, Au, Pt nanoparticles supported on TiO2 nanotubes were small and well dispersed on the surface of the TiO2 nanotubes. UV-Vis absorption spectra showed that the absorbance of Ag/TiO2 nanotubes and Au/TiO2 nanotubes in the visible light range increased greatly compared to the single titania nanotubes.
