In this work, a nonthermal, continuous-flow approach for the preparation of γ-manganese oxide (γ-MnO2) and cerium oxide (CeO2) microspheres has been developed. By this technique, γ-MnO2 materials with surface areas of 240, 98, and 87 m2/g and CeO2 microspheres with a surface area of 1 m2/g have been fabricated successfully. Characterization of the materials was carried out using powder X-ray diffraction, infrared and inductively coupled plasma optical emission spectrometer (ICP/OES), nitrogen sorption, scanning electron microscopy, transmission electron microscopy, and thermogravimetric analysis. The synthesized materials showed good catalytic activity in the oxidation of α-methyl styrene.enMorphologyElectromagnetic radiationionsArticle
