“…Most researchers have studied the catalytic behavior of zinc manganite composites, for example, ZnMn 2 O 4 /ZnO [ 43 ], ZnMn 2 O 4 /ZnS/ZnO/PVP [ 44 ], ZnMn 2 O 4 /MnO 2 [ 45 ], ZnMn 2 O 4 /Mg [ 46 ], ZnMn 2 O 4 /TiO 2 [ 47 ] composites. In this work, we study the photocatalytic behavior of ZnMn 2 O 4 nanostructures for the methyl violet (MV), erythrosine (ES), and eriochrome Black T (EBT) degradations, for the first time.…”
