Natural assembly method was utilized to prepare a novel ternary Ag-SnS-TiO nanocomposite, in which TiO nanobelts were used as templates. The co-loading of Ag and SnS nanoparticles endows TiO nanobelts with enhanced photocatalytic capability, resulting from the broadened light absorption spectra and decreased band gaps. Comparing with raw TiO nanobelts and commercial Degussa P25, an improvement in photodegradation of simulated organic pollutants was successfully demonstrated due to the decreasing recombination of photogenerated electron-hole pairs. Our work presents a new strategy for the preparation of ternary TiO-based photocatalysts in the practical application of wastewater treatment.
采用自然组装法制备了一种新型三元Ag-SnS-TiO纳米复合材料，其中TiO纳米带用作模板。Ag和SnS纳米颗粒的共负载赋予TiO纳米带增强的光催化能力，这源于拓宽的光吸收光谱和减小的带隙。与原始TiO纳米带和商用Degussa P25相比，由于光生电子-空穴对的复合减少，成功证明了模拟有机污染物光降解性能的提高。我们的工作为三元TiO基光催化剂在废水处理实际应用中的制备提供了一种新策略。
