Abstract: A type of uniform ZnMn2O4 with cubic-like morphology was successfully synthesized by a facile solvothermal method. The results from X-ray powder diffraction, scanning electron microscope and Xray photoemission spectroscopy indicated that the as-prepared sample was cubic-like ZnMn2O4 with well crystallinity and phase purity. The average length, width and thickness of the sample are approximately 2.5 mu m, 1.5 mu m and 1.5 mu m, respectively. The N-2 gas adsorption-desorption isotherms results revealed that the cubic-like ZnMn2O4 has a higher surface area of 138 m(2) g(-1) and monomodal pore size distributions. The optical property of the sample was studied by UV-vis diffuse reflectance spectroscopy. The synthesized cubic-like ZnMn2O4 exhibited excellent photocatalytic activity for rhodamine B under visible-light irradiation. (C) 2012 Elsevier B.V. All rights reserved.
