Comparative analysis of photocatalysts from de-ironing plant wastes

Summary

The results of the synthesis of photocatalysts prepared from de-ironing plant wastes are presented. To improve the efficiency, iron-containing materials were doped with zinc, molybdenum, and lanthanum. For the synthesis, the method of solution combustion synthesis was chosen. Urea, citric acid and glycine in stoichiometric ratio were taken as reducing agents. The obtained samples were studied by X-ray phase analysis. The efficiency of the obtained materials was studied in the process of photocatalytic destruction of four dyes of different origin. Based on the results of the work, the optimal compositions and reducing agents used for their synthesis were determined.
