High efficient photocatalytic degradation of Malachite green using visible-light- driven TiO2/CDs/Polyaniline photocatalyst

Providing novel photocatalysts with high photocatalytic efficiency is of great significance. In the present work, the TiO₂/CDs/Polyaniline (20%) nanocomposite as efficient visible-light-driven photocatalyst was fabricated using a facile method. Photocatalytic ability of the nanocomposite was evaluated by photocatalytic removal of Malachite green under visible-light illumination. The results demonstrated that the TiO₂/CDs/Polyaniline (20%) nanocomposite exhibited remarkably enhanced photocatalytic activity, which was approximately 32.7, 3.4, and 9.4 times higher than the pure TiO2, TiO2/CDs (0.5mL) and TiO2/Polyaniline (20%) photocatalysts
