Abstract

The present work deals with the synthesis, characterization, and photocatalytic degradation of PrO2–MgO nanocomposite where it was formed by the green approach. Following the synthesis, many different kinds of instrumental analysis for the investigation of crystal structure, morphology, size, shape, elemental analysis, optical properties, etc. For the efficiency testing of PrO2-MgO, the photocatalytic degradation of methylene blue dye in the presence of visible light was used and for that, the spectrophotochemical technique was employed. The rate of dye degradation in accordance with the changes in solution pH, dye concentration, photocatalyst amount, and light intensity was measured, where the results supported 100 % degradation under the optimum conditions. © 2020 Elsevier GmbH
