The Improved Photocatalytic Properties of Methylene Blue for V_(2)O_(3)/CNT/TiO_(2) Composite under Visible Light

摘要

Multiwall carbon nanotube (MWCNT), vanadyl acetylacetonate (V(acac)_(3)), and titanium n-butoxide (TNB) were used as carbon, vanadium oxide, and titanium oxide precursor to prepare V_(2)O_(3)/CNT/TiO_(2) composite. The obtained composite was characterized by BET surface area measurement, X-ray diffraction, transmission electron microscopy, and energy dispersive X-ray analysis. In addition, we used methylene blue (MB) solution under condition of visible light irradiation to determine their photocatalytic degradation efficiency. In conclusion, the V_(2)O_(3)/CNT/TiO_(2) composite had excellent photocatalytic degradation for MB solution under visible light.
