Enhancing photocatalytic performance of SnO2/ZnS nanocomposites synthesized via dual-step precipitation and ultrasonicated hydrothermal route

SnO₂/ZnS nanocomposites were successfully synthesized using a modified hydrothermal route. The synthesis involved separate co-precipitation of SnO₂ and ZnS, followed by ultrasonic stirring and hydrothermal treatment. The resulting nanocomposites exhibited controlled size and composition. By adjusting synthesis parameters such as the molar ratio of Sn to Zn, reaction temperature, and reaction time, the morphology and properties of the nanocomposites could be finely tuned. The synthesized SnO₂/ZnS nanocomposites demonstrated remarkable improvements in photocatalytic performance compared to pure SnO₂ or ZnS nanoparticles. This enhancement was attributed to the nanocomposites' enhanced charge separation, increased surface area, and improved light absorption capabilities. As a result, the SnO₂/ZnS nanocomposites hold great promise for a wide range of applications, including environmental remediation, water splitting, and solar energy conversion.
