Abstract
Mixed metal oxides (TiO2/WO3) containing polythiophene binder were prepared. The molar ratios of TiO2/WO3/thiophene used for an in situ polymerization were varied from 1/2/0 to 1/2/0.6. Catalytic activities of the metal oxides were studied by following up the degradation of methylene blue under various illumination conditions. With the presence of the polymeric binder in the system, the activity in the dark was induced whereas those under both UV and visible light were maintained. The amount of polymer also played a role. The catalytic activities decreased with increasing monomer content. The results are discussed in light of morphology characterized by TEM-EDX.
