英文摘要	A novel "cage-like" hollow sio2 microspheres with porous walls were synthesized by self-assembly of silica species with vesicles of cetyltrimethyl ammonium bromide (ctab) adsorbed on polystyrene(ps) templating spheres, thus removing the ps and ctab. sem and tem analysis show walls of the as-synthesized "cage-like" hollow sio2 microspheres were built by interconnecting sio2 nanoparticles(similar to 90nm), and pores (20 similar to 880 nm) from stacked sio2 particles were also discerned. saxrd and bet measurements suggested these sio2 nanoparticles stacked on the walls of hollow spheres were characterized with mcm-41 type ordered porous structure.
