Superfine cuprous oxide (Cu 2 O) spheres with smooth surface have been successfully synthesized by using gelatin as template. The possible mechanism for the formation of superfine Cu 2 O sphere is revealed. The results of X-ray diffraction (XRD), scanning electron microscopy (SEM) and Transmission electron microscope (TEM) indicated that the as-obtained powder was cubic structure, pure, uniform, monodispersed Cu 2 O spherical polycrystalline with smooth surface. What’s more, the photocatalytic activity of the superfine Cu 2 O spherical polycrystalline is investigated under visible light irradiation. It is worth noting that the superfine Cu 2 O microspheres have a highly selective adsorption for anionic dyes, such as methyl orange, and the mechanisms of absorption were mainly attributed to electrostatic adsorption.
