Low temperature in air molten synthesis of flower-like hierarchical structure SnS2 with superior photocatalysis

A molten method with the characteristics of low temperature, air environment, simplicity, cost-effectiveness and easy scale-up, was tried for the synthesis of highly photocatalytically active SnS2. By heating the ground mixture of low-melting-point S and SnCl2•2H2O powders in air at 120 °C for 6 h, phase-pure SnS2 with a nanoflake-assembled flower-like hierarchical structure was obtained. The phase, purity, microstructure, and bandgap of the...
