Polystyrene spheres were prepared by soap free emulsion polymerization method. The effects of styrene concentration, polymerization time and self-assemble methods on the diameter of the polystyrene spheres were investigated. Different size of polystyrene microspheres could be obtained by changing styrene concentration and polymerization time. Polystyrene templates with good uniform and highly ordered can be assembled by means of vertical deposition method. Based on this template, three-dimensional ordered macroporous (3DOM) perovskite-type oxides LaFeO3 were successfully prepared which were confirmed by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was also found that 1mol/L metal precursor solution which used ethanol solution of metal nitrates with citric acid addition gave the best 3DOM perovskite-type LaFeO3 oxides. The pores are uniform, flexible and arranged in a highly ordered form.
