With coaxial nozzle system,TiO2 hollow spheres were prepared and the optimum parameters of forming TiO2 hollow spheres were fix on as follows: acrylamide (AM) was used as monomer up to 30.3%,acetone was used as vesicant,the mass fraction of initiator was 0.4%,the forming temperature was in the range from 90 ℃ to 95 ℃. The photocatalistic performance of TiO2 hollow spheres was characterized by degradation of methyl orange. Compared with nano-TiO2 powders,hollow spheres can be recycled after cleanout and drying,taking on similar efficiency of photocatalistic.
