摘要
本研究以Degussa P-25 二氧化鈦粉末為載體,使用光催化沈積法來製備含鉑(Pt)及銅(Cu)的金屬/二氧化鈦觸媒。並以浸漬覆膜(dip-coating)及旋轉覆膜(spin-coating)兩種方法將之轉鍍在氧化銦錫(ITO)基材表面上形成薄膜。經由掃描式穿隧顯微鏡(STM)的鑑定,來探討金屬/二氧化鈦催化薄膜上之分散度及其與製備條件、鍍膜方式等的相關性,最後利用二硫化物的分解反應來穩定此薄膜的光催化效能。

ABSTRACT
The platium- and copper- modified titanium oxide (Pt-TiO2 and Cu-TiO2) particles have been successively made by photocatalytic deposition on Degussa P-25, those photocatalytic particles are deposited onto the indium tin oxide (ITO) substrate to form thin films of Pt-TiO2 and Cu-TiO2 by means of dip-coating and spin-coating processes. The morphology, microstructure, crystalline structure, the dispersion of Pt/TiO2 and Cu/TiO2,chemical composition, and the correlation between these factors and the coating condition of such prepared thin films have been investigated using the combination techniques of scanning tunneling microscopy (STM)。
