As an efficient green water disinfection technology, photothermal synergy sterilization has been paid more attention in recent years with its immeasurable advantages. The development of photocatalysts for efficient sterilization is currently an urgent need. In this manuscript, pure Ti₃C₂T_x is first studied as a photothermal synergy sterilization material and shows an excellent sterilization effect. The sterilization rate of Escherichia coli (E. coli) reaches 99.9% under visible infrared (vis-IR) light for 40 minutes. The peeling of the Al layer from Ti₃AlC₂ is the fundamental reason for improving the photothermal conversion ability, and photogenerated free radicals have also proved to be improved. The dilution spreading plate method, enzyme activity test, and leakage of cell contents confirmed the complete death of bacteria. Two aspects, photogenerated free radicals and photothermal synergy, were carried to illuminate the mechanism.

纯Ti3C2Tx在抗菌反应中的光热协同作用及其机理

作为一种高效的绿水消毒技术，光热协同消毒以其不可估量的优势近年来受到了越来越多的关注。当前迫切需要开发用于有效灭菌的光催化剂。在此手稿中，首先研究了纯Ti ₃ C ₂ T _x作为光热协同杀菌材料，并显示出优异的杀菌效果。大肠埃希氏菌（E. coli）在可见红外（vis-IR）光下灭菌40分钟达到99.9％。从Ti ₃ AlC ₂剥离Al层这是提高光热转化能力的根本原因，并且光生自由基也得到了改善。稀释铺板法，酶活性测试和细胞内含物泄漏证实细菌完全死亡。从光生自由基和光热协同两个方面阐明了这一机理。
