Nanosize Au鈥揟iO2 is becoming popular to photocatalytic application in visible light. A new fabrication process of photocatalyst is introduced for the purpose of its potential utilization under sunlight. A mixture of photocatalyst and polycarbonate (PC) was cast on a glass substrate to form a film. The photocatalytic experiment was performed in the UV region and visible region separately with powdery samples first, followed by composite films. When powdery Au鈥揟iO2 was applied to decompose of acetaldehyde, activity inferior to Degussa P-25 was observed in UV light, but superior activity was observed in visible light. In the case of Au鈥揟iO2 in PC composite film, evidence of acetaldehyde decomposition was observed, unlike the case of P-25 in PC composite, which showed negligible traces of acetaldehyde decomposition.
