摘要：
Cr2O3–CNT/TiO2 composites derived from chromium acetylacetonate, multi-walled carbon nanotubes (MWCNT) and titanium n-butoxide (TNB) were prepared, and the photocatalytic activity of the Cr2O3–CNT and CNT/TiO2 composites was examined. The Cr2O3–CNT/TiO2 composites were characterized by BET surface area measurement, X-ray diffraction, transmission electron microscopy, and energy dispersive X-ray analysis. The photocatalytic activity was determined from the decomposition of methylene blue (MB) under visible light irradiation. Methylene blue was photodegraded successfully in the presence of the Cr2O3–CNT/TiO2 composite under visible light irradiation.
