摘要：

The effect of conducting polymer matrix, polyaniline (PANI) on the photocorrosion and photochemical activities of Black Anatase Titania (BAT) has been systematically investigated. PANI-BAT composite has been fabricated by a modified hydrothermal method and successive in situ polymerization of aniline. This hybrid material has shown excellent photo catalytic activity than BAT under visible light. The rate constant value of dye degradation in presence of the PANI-BAT composite was found 2.4 x 10(-2) min(-1), which is 1.5 times. greater than that of the commercially available photocatalyst Degussa P25 and BAT. The study unveils the strong correlation between electrochemical impedance measurements and the photochemical results.
