鈦酸鍶材料在光催化降解有機物及光催化產氫領域有廣泛的應用，本研究利用鈦酸鍶材料，做有機光催化應用將伯胺分子氧化耦合合成亞胺分子，這是一個新穎的策略。鈦酸鍶材料具備合成容易、合成時間短、及合成成本低等優點，且光催化化學是一種綠色化學與環境友善的方法。在控制實驗，可知光源、氧氣對反應的重要性，並且在最佳條件實驗下，乙腈為最佳溶劑，用不同晶面之鈦酸鍶立方體和{110}-截角立方體以及{100}-截角菱形十二面體，結果是{100}-截角菱形十二面體具有最好的光催化活性，產率可達100%。我們也做了不同官能基的胺類進行氧化耦合反應，發現在推電子基官能基可獲得良好的產率，在雜環類的分子，也有不錯的產率。此外，鈦酸鍶材料具有良好的穩定性，可以在重複三次反應後仍具有量好產率，最後根據自由基和電子電洞捕捉劑實驗，以及EPR實驗提出一可能的反應機制。

SrTiO3 material has a wide range of applications in the fields of photocatalytic degradation of organic compounds and photocatalytic hydrogen production. Here we utilized SrTiO3 material for oxidative coupling of amine molecules to synthesize imine molecules, which represents a novel strategy. SrTiO3 material possesses advantages such as easy synthesis, short synthesis time, and low synthesis cost. Additionally, photocatalytic chemistry is a green and environmentally friendly method. In the controlled experiments, we determined the significance of the light source and oxygen for the reaction. Under the optimal conditions, acetonitrile was identified as the best solvent. Using different crystal faces of cubes and {110}-truncated cubes and {100}-truncated rhomboid dodecahedra of SrTiO3, the {100}-truncated rhombic dodecahedron exhibited the highest photocatalytic activity, with a yield of up to 100%. We also conducted oxidative coupling reactions of amines with different functional groups and found that electron donating functional groups resulted in good yields. Satisfactory yields were also obtained for heterocyclic molecules. Furthermore, SrTiO3 material demonstrated excellent stability, maintaining high yields even after three repeated reactions. Finally, based on experiments involving radical and electron-hole scavengers, as well as electron paramagnetic resonance (EPR) experiments, a possible reaction mechanism was proposed.
