Urchin-like hollow SiO₂@γ-MnO₂ microparticles for the rapid degradation of organic dyes.

ABSTRACT: In this paper, using hollow silica microspheres as carriers, we developed a facile one-pot method for the preparation of hollow SiO₂@MnO₂ composite microparticles. Under a certain proportion of hollow silica microspheres and manganese salt, a novel kind of hollow urchin-like SiO₂@γ-MnO₂ microparticles was obtained. The structure and morphology of the composite microparticles were characterized by XRD, SEM and TEM. On this basis, using rhodamine B and methyl orange as model molecules, the oxidative degradation ability of the hollow SiO₂@γ-MnO₂ microparticles for organic dyes in water was investigated through UV-vis analysis technology. The urchin-like SiO₂@γ-MnO₂ microparticles showed excellent performan
