Photocatalytic Evaluation of the Ternary Composite CdSO4-ZnAl LDH/ZnS in Hydrogen Production without a Sacrificial Reagent

In this work, a layered double hydroxide support modified with cadmium was synthesized by one-pot coprecipitation method. Then, it sulfured in different percentages solvothermal Next, the samples were analyzed using various characterization techniques like XRD, DRS, FTIR, N2 physisorption, PL spectroscopy, TEM, and SEM. Finally, uncalcined materials assessed hydrogen production from water methanol-water solution under UV-light irradiation. The results showed that sulphuration improves photocatalytic activity, reaching maximum rate constant of 7403 µmol/g∙h 1326 water.
