| 摘 要： | 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 ofphotocatalistic.
