【Abstract】 The nano\|sized TiO\-2 of deferent structure were prepared with Sol\|Gel method.The photocatalytic oxidation of phenol in water was used as a model reaction for evaluating the activity of TiO\-2 catalysis which was immobilized on porous nickel.The result showed that nano\|sized anatase TiO\-2 has a higher photocatalytic activity than nano\|sized TiO\-2 with composite structure of anatase and rutile.更多还原
