摘要

表面電漿光觸媒讓外加光源延伸拓展至可見光甚至紅外波段進行光催化作用的特性，促使科學家想方設法運用取之不盡的太陽光全波段來做光觸媒的環境與能源應用。於是光觸媒汙水處理、水分解產氫、光催化還原CO2生產碳氫化合物等應用於焉而生。本研究專門設計低價且高效率光觸媒旋轉反應器。並在光碟片基板上合成銀/氧化鋅奈米結構當作固定床光觸媒。進一步實驗證明銀/氧化鋅奈米光觸媒光碟旋轉反應器的光催化效能。

Plasmonic photocatalysis has recently made rapid progress in enhancing the photocatalytic efficiency under visible light irradiation, raising the hope to directly use the sunlight for environmental and energy applications such as wastewater treatment, water splitting and carbon dioxide reduction. A low-cost and efficient photocatalytic reactor for environmental treatment and green technology was presented. Ag/ZnO nano structure firmly growing on polycarbonate substrate (DVD-RW) are generally perpendicular to the substrate as the immobilized photocatalyst of the spinning disk reactor. The photocatalytic efficiency and durability of the Ag/ZnO nanostructure were tested and proven.
