鑒於環境保護意識的日漸提升，近年來綠色化學已成為化學的研究主流，其中的一個分支為使用環境友善的催化劑進行光催化需氧氧化反應。本研究使用以4-硝基乙炔苯修飾的氧化亞銅菱形十二面體做為催化劑，水及甲醇作為溶劑，在藍光照射下以及氧氣環境中催化芳香硫醚氧化反應。4-硝基乙炔苯修飾氧化亞銅的程序能使產率由58%大幅提升至97%，一連串的控制實驗也測試了溶劑、反應氣體以及溫度的影響。接著我們將帶有不同芳香取代基的硫醚作為此反應的起始物，發現大部分的反應都能有不錯的產率及選擇性。最後再藉由一系列的活性物質捕捉實驗以及EPR實驗提出了可能的反應結構。

In view of the increasing awareness of environmental protection, green chemistry has become the mainstream of chemical research recent years, one of which is the use of environmentally friendly catalysts for photocatalytic aerobic oxidation reactions. In this study, 4-nitrophenylacetylene (4-NA)-modified Cu2O rhombic dodecahedra were used as catalyst, and water and methanol were used as solvents to catalyze the oxidation of aryl sulfides under blue light irradiation and oxygen environment. Compared to pristine Cu2O rhombic dodecahedra, surface 4-NA modification can significantly increase the yield from 58% to 97%. We then used thioanisoles with different aromatic substituents as starting materials for this reaction, and found that most of them have good yields and selectivity. Finally, through a series of active species capture experiments and EPR experiments, a possible reaction structure is proposed.
