Abstract

The electrochemical anodic oxidation method was used to prepare thin films of titanium dioxide (TiO2) semiconductors (undoped and doped with Mn). These films were used to test the oxidation of methanol (CH3OH), the degree of which was quantified by measuring the current density produced as a function of an applied potential between 0.5 V and 5.0 V. The value of the potential to be applied in order to prevent fast electron-hole recombination was determined. The observed phenomenon is explained by considering the wave nature of the electron.
