| Abstract: | Natural assembly method was utilized to prepare a novel ternary Ag–SnS–TiO2 nanocomposite, in which TiO2 nanobelts were used as templates. The co-loading of Ag and SnS nanoparticles endows TiO2 nanobelts with enhanced photocatalytic capability, resulting from the broadened light absorption spectra and decreased band gaps. Comparing with raw TiO2 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 TiO2-based photocatalysts in the practical application of wastewater treatment.Natural assembly method was utilized to prepare a novel ternary Ag–SnS–TiO2 nanocomposite, in which TiO2 nanobelts were used as templates. |
