摘要
本文用溶胶 凝胶法制备了不同晶相的TiO2 纳米晶 ,将其负载于镍网上 ,以苯酚的降解为模型反应 ,研究对比了不同晶相TiO2 纳米晶的光催化活性。结果表明 ,纯锐钛矿相的TiO2 纳米晶的降解能力要强于锐钛矿与金红石混合相的TiO2
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.
