• generated CO2 were measured for both catalysts. These inexpensive semiconductor materials, which proved to be light-responsive, can be further used for developing water depollution technologies based on solar light energy. Keywords: microwave-assisted synthesis; oxalic acid mineralization; semiconductor

• photocatalysts; water depollution; Introduction Over the past decades, significant research has been focused on designing and preparing nanostructures of various shapes and sizes, which exhibit unique properties and potential applications [1]. Considerable advancements have been made in synthesizing

• ample opportunities for future investigations despite the large number of such data already reported on ZnO materials. Mn-doped ZnO materials synthesized by SG and its derivative methods can be successfully used for photodriven oxidation processes and water depollution since they are inexpensive, not
