金屬－二氧化鈦複合材料為光觸媒化學研究的重點方向之一。本研究利用一簡單光輔助還原法在二氧化碳奈米顆粒 (TiO2 NPs) 上修飾白金奈米顆粒 (Pt NPs) 與白金薄膜，並比較在不同白金分布形貌之白金－二氧化鈦複合電極上，其光輔助甲醇氧化能力。研究結果顯示，Pt NPs 修飾之二氧化鈦電極其半反應電流在照光後有接近 50% 的提升，其提升幅度大於白金薄膜修飾之二氧化鈦複合電極。

Metal-titanium oxide composite material is one of the emerging research fields in photochemistry. In this study,platinum nanoparticles (NPs) and Pt thin film were coated on TiO2 NPs by adopting a simple photo deposition
approach. The capabilities for photo enhanced methanol oxidation on electrodes with different types Pt coated TiO2 were investigated. In methanol oxidation test, the oxidation current found on the Pt NPs modified TiO2 electrode was magnificently boosted by about 50%, comparing to that of Pt thin film coated ones.
