Catalytic and structural investigations of nano-sized zinc manganite (ZnMn2O4) powders have been determined. These manganites were prepared by precipitation–deposition route followed by heating at 400, 600, and 800℃. The final products were characterized X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive X-ray (EDX). The catalytic activity of the as prepared systems was measured by the hydrogen peroxide decomposition in aqueous solution over the solid surface at 30–50℃. The results showed that the calcination temperature affects the different characteristics of the investigated solids.
