Low Temperature Solid-state Synthesis of Tin Sulfide Hierarchical Architectures and Their Excellent Photocatalytic Activities
Tin sulfide hierarchical flower-like architectures were successfully prepared by a facile low temperature synthetic route. The as-prepared samples were characterized by the X-ray diffract ion (XRD), field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM). The observation of FESEM and HRTEM showed that tin sulfide hierarchical flower-like architectures are of porous structure and composed of numerous nanoplates, which are randomly arranged and interconnected with each other. The photocatalytic activities of the as-prepared samples under visible light irradiation (λ>420 nm) were evaluated by the degradation of rhodamine B (RhB). The effect of heat-treatment temperatures on the photocatalytic efficiency of the as-prepared samples was investigated. The result showed that tin sulfide hierarchical flower-like architectures treated at the temprature of 90 °C exhibited the highest photocatalytic efficiency.
