Heteropolyacid-chitosan/TiO2 composites were modified by the conducting polymers and synthesized via a solvothermal method. The conducting polymers were prepared via the synthesis of heteropolyacids (H3PMo12O40, H3PW12O40, H4SiW12O40) and chitosan. It was found that the conducting polymers (heteropolyacids-chitosan) could improve the photocatalytic activity of TiO2 a lot, and the H3PMo12O40-chitosan/TiO2 sample possessed the highest photocatalytic activity among the composite samples. The compound photocatalysts were characterized by X-ray diffraction, UV-Vis diffuse reflectance spectra, Fourier transform infrared spectroscopy and scanning electron microscopy.
