| Outline of Final Research Achievements |
The thermal balance enable to irradiate light was built for the analysis of the simultaneous photo- and thermal-decomposition of adsorbates. As a result of the simultaneous decomposition of methylene blue on anatase titania, the ultraviolet irradiation was found to increase the reaction rate effectively. Au-TiO2 composite catalysts were then prepared from HAuCl4 and titanium-iso-propoxide by sol-gel method with and without the addition of reduction agent (ascorbic acid). The absorption of visible light by the addition of Au nanoparticles was confirmed from the result of the diffuse reflectance spectrophotometry. The Au-TiO2 composite was found to be useful as a photocatalyst for the methylene blue degradation and the photochemical reduction of nitrobenzene under visible light irradiation.
