Abstract

Nano-TiO₂ electrode was prepared by sol-gel method, and then applied the electrode to the electropolymerization of 3-methylthiophene. The properties of the composite film were studied by cyclic voltammetry (CV), UV-vis absorption spectra, scanning electron micrographs (SEM) and electrochemical impedance spectrum. Poly(3-methylthiophene) (PMT) film was obtained successfully and showed obvious doping and dedoping process. The in situ UV-vis spectra showed the transition peaks of oxidation and reduction states. In the reduction (dedoping) process, the electrode exhibited an absorption peak at 480 nm, while the peak disappeared in the oxidation (doping) process, replaced by an increasing visible light absorption. The p-n heterojunction existed in the nano-TiO₂/PMT film electrode, which can improve the photon-electron conversion efficiency. The EIS spectrum presents the conductivity of the composite film.

Key words: ionic liquid, 3-methylthiophene, nano-TiO₂, cyclic voltammetry, impedance
