It is necessary to explore the best treatment to eradicate trimethylamine [TMA] in air, since it is toxic and hazardous to the living organism. Photocatalysis, a low-cost and environmentally friendly technology, has been studied in comparison with photo-electrochemical catalysis in the removal of TMA gas. In this study, it is most quickly and efficiently degraded using Co-MoS₂ composite catalyst in an integrated system of (PEC) photo-electrochemical catalysis. The performance of the catalyst and system was evaluated by TMA removal ratio. As a result, the catalyst has good degradation performance for TMA in the PEC system, which indicates that it has high photocatalytic activity and high apparent quantum efficiency. In addition, the stability of the Co-MoS₂ catalyst in the PEC is better than in PC due to the presence of the external bias generated by the assisted electrochemistry in the PEC system.

有必要探索消除空气中三甲胺[TMA]的最佳方法，因为它对生物体有毒且有害。与光电化学催化去除TMA气体相比，光催化是一种低成本且环保的技术。在这项研究中，在（PEC）光电化学催化的集成系统中，使用Co-MoS ₂复合催化剂可以最快速，最有效地降解它。通过TMA去除率评估催化剂和体系的性能。结果，该催化剂对PEC体系中的TMA具有良好的降解性能，这表明它具有高的光催化活性和高的表观量子效率。此外，Co-MoS ₂的稳定性 由于PEC系统中辅助电化学产生的外部偏压的存在，PEC中的催化剂比PC中的催化剂更好。
