1T-MoS is in situ grown on TiO nanotubes (TNTs) using a hydrothermal method, forming a 1T-MoS@TNTs composite, which is confirmed by its physical characterization. The prepared composites show enhanced photocatalytic performance for the degradation of tetracycline hydrochloride under visible light, and the improved photocatalytic activity is closely related to the loaded amount of 1T-MoS. Therein, 0.5 wt % 1T-MoS@TNTs can degrade 57% in 1 h, which is the highest photocatalytic efficiency observed in experiments so far. It is speculated that the introduction of 1T-MoS may optimize light absorption and charge separation/transport. The active species are identified and the reaction mechanism is proposed here.
采用水热法在二氧化钛纳米管（TNTs）上原位生长1T-二硫化钼，形成1T-二硫化钼@TNTs复合材料，这通过其物理表征得到证实。所制备的复合材料在可见光下对盐酸四环素的降解表现出增强的光催化性能，且光催化活性的提高与1T-二硫化钼的负载量密切相关。其中，0.5 wt%的1T-二硫化钼@TNTs在1小时内可降解57%，这是迄今为止实验中观察到的最高光催化效率。推测1T-二硫化钼的引入可能优化了光吸收以及电荷分离/传输。本文确定了活性物种并提出了反应机理。
