| Research Abstract |
We prepared new visible-light sensitive photocatalytic cells composed of both TiO_2/WO_3 and Pt nano-particles/WO_3 films. The cells were activated two different hole-electron charge separations. In this study, we also prepared another cell usedα-Fe_2O_3 instead of WO_3 because Fe is very cheap and lies under the ground in large quantities. Theα-Fe_2O_3 type cells is little inferior to the WO_3 type ones in the rate of the methanol decomposition. This is mainly due to the different decomposition mechanism because the intermediate products are different at both cases.
