Fabrication, characterization and photocatalytic capability of ZnAl2O4 nanospheres
MetadataShow full item record
Developing photocatalysts with specific morphology promises good opportunities to discover the geometry dependent properties. Porous and spherical shaped superstructure of ZnAl2O4 was successfully synthesized by a facile wet chemical solution-phase method. Their surface morphology and structure were investigated by X-ray powder diffraction, scanning electron microscopy, energy dispersive spectra and Brunauer-Emmet-Teller N2 gas adsorption-desorption isotherms. The optical property of the ZnAl2O4 nanospheres were studied by UV-vis diffuse reflectance spectroscopy. The ZnAl2O4 nanospheres exhibited a good photocatalytic activity in degrading rhodamine B.
