Abstract:
Polyaniline-modified nanocrystalline TiO 2 composites were successfully prepared by in situ chemical oxidative polymerization and used as an efficient photocatalyst for the degradation of methyl orange under natural light. The nanocomposites were characterized by Transmission electron microscope (TEM), Scanning electron microscope (SEM), Fourier transform infrared spectra (FT-IR), X-ray diffraction and UV-Vis spectra. Results show that polyaniline-modified nanocrystalline TiO 2 composites exhibit significantly higher photocatalytic activity than that of neat TiO 2 on degradation of methyl orange under natural light. In addition, the conductivity of polyaniline-modified TiO 2 nanoparticles was also investigated and has reached 2.65 × 10 -1 S cm -1 at room temperature.
