ZnIn2S4 was prepared by urea-thermal synthesis method for photocatalytic hydrogen evolution

In this study, we developed a urea-thermal synthesis method featuring simple operation, and successfully prepared pure-phase ZnIn 2 S 4 materials by regulating different holding durations. The experimental results showed that at a reaction temperature of 180°C, only 2 h of heat preservation is required to obtain ZnIn 2 S 4 particles that completely match the standard card. All samples prepared with different reaction durations exhibited excellent photocatalytic activity. Beyond developing a simplified synthetic route for ZnIn 2 S 4 photocatalysts, this work offers new research approach to the synthesis and application of photocatalytic materials.
