J. Cent. South Univ. Technol. (2010) 17: 755-759 DOI: 10.1007/s11771-010-0552-y Photocatalytic activity of bauxite-tailings supported nano-TiO2 LU Qing-hua(卢清华) , HU Yue-hua(胡岳华), WANG Meng(王梦... of phenol concentration under different illumination time. Effects of the calcination temperature, the pH and the cycles on the photocatalytic activity of TiO2/BTs composites were investigated......
reflectance spectroscopy. The Fe-doped CuO sample shows higher adsorption capacity and photocatalytic activity for xanthate degradation than pure CuO under visible light irradiation. In addition... degradation, and the apparent rate constant ( k ) was calculated. The value of k for Fe-doped CuO is 1.5 times that of pure CuO. The higher photocatalytic activity of Fe-doped CuO is attributed......
