Tóm tắt

 TiO2-polyaniline (PANI) composites were prepared by thermal oxidation of titanium substrate combined with chemical polymerization of aniline. Their chemical structures were determined by infrared (IR) spectroscopy and x-ray analysis. Their morphological structures were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Their electro- and photoelectrochmical properties were examined by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) analysis. The results showed that their photoelectrochemical behavior was better than that of TiO2 electrode
  among them the more PANI existed in composite the higher was the anodic photoelectrochemical current. It was also found that the composite has structure in the range of nanosize.
