| description | Previous studies have displayed various conclusions about the effect of preparation factors on the photoreduction property of ZnIn<sub>2</sub>S<sub>4</sub>. Therefore, it is not easy to figure out the optimal preparation conditions of ZnIn<sub>2</sub>S<sub>4</sub> for Cr(VI) photoreduction. To ensure Cr(VI) reduction efficiency, various ZnIn<sub>2</sub>S<sub>4</sub> photocatalysts were prepared in different solvents (i.e., water and ethylene glycol) and temperatures (i.e., 120 °C, 150 °C and 180°C). Different characterization methods were used to explain the difference in optical performance and photocatalytic property among the obtained samples. The results show that all the samples exhibit a similar band gap. The reaction solvent and temperature have a great influence on the surface morphology and optical property, leading to the different photocatalytic properties. ZnIn<sub>2</sub>S<sub>4</sub> synthesized at 120 °C in the solvothermal condition shows the optimal efficiency on Cr(VI) photoreduction due to the effective utilization of photo-induced carriers. The reasonable analysis and effective conclusion presented may provide the optimal synthesis method of ZnIn<sub>2</sub>S<sub>4</sub> to effectively remove Cr(VI) from water environment. |
