摘要：
CdSe-modified rutile TiO2 nanocrystals with mercaptoacetic acid as a stabilizer were prepared by the hydrothermal method. The photoactivities; of the new photocatalyst under visible light illumination were demonstrated by the degradation of methylene blue (MB). The effects of CdSe content on the absorption spectra and photoactivities were discussed. After sensitization, TiO2 significantly responded to visible light illumination and the visible light photoactivities also increased.
