中文摘要	a facile method is proposed for the synthesis of three-dimensional (3d) flower-like co3-xfexo4 ferrite (cf) hollow spheres, using sio2@feooh as precursor. the cf hollow spheres are efficient for the catalytic degradation of methylene blue (mb) in the presence of h2o2 at 80 degrees c. the obtained cf hollow spheres were characterized using transmission electron microscopy, field emission scanning electron microscopy, x-ray diffraction, x-ray photo-electron spectroscopy, and n-2 adsorption-desorption isotherm measurements. the formation of 3d hierarchical flower-like superstructure was influenced by the relative amount of urea used. as the mole ratio of cocl2 and urea decreased, the structure of the products was tailored from yolk-like spheres to hollow spheres with different sized void interiors. moreover, n-2 adsorption-desorption isotherm analysis showed that the cf hollow spheres have a large specific surface area (163 m(2) g(-1)) which provided more activity sites. the cf hollow spheres can catalyze the oxidation of mb efficiently. these results indicate that the designed cf hollow spheres exhibit promising capability for the degradation of dyes.
