SEM micrographs showed that the PS colloidal crystal template spheres (diameters 275±10 nm) arrayed into hexagonally close-packed layers. The synthesized 3DOM SnO2 microparticles were circularly or hexagonally porous and the thin porous walls were formed by nanocrystals of SnO2. The macroporous diameters of the 3DOM SnO2 were between (215±10) nm and the thicknesses of the porous walls was between 20～30 nm.
