以四氯化钛为前驱体,采用水解沉淀法在海泡石粉体上负栽纳米TiO_2.用X射线衍射仪和扫描电子显微镜等时TiO_2/海泡石复合结构进行了表征;并以甲醛为降解对象,考察了TiO_2复合材料的光催化性能.结果表明:纳米TiO_2/海泡石复合粉体在650℃煅烧后TiO_2为锐钛矿型,在紫外光照射下,对甲醛气体具有良好的降解效果.
以四氯化鈦為前驅體,採用水解沉澱法在海泡石粉體上負栽納米TiO_2.用X射線衍射儀和掃描電子顯微鏡等時TiO_2/海泡石複閤結構進行瞭錶徵;併以甲醛為降解對象,攷察瞭TiO_2複閤材料的光催化性能.結果錶明:納米TiO_2/海泡石複閤粉體在650℃煅燒後TiO_2為銳鈦礦型,在紫外光照射下,對甲醛氣體具有良好的降解效果.

The nano-TiO_2 was loaded on the supporting body of sepiolite particles by the hydrolysis precipitation method using TiCl_4.And the TiO_2/sepiolite composite structure was characterized by X-ray diffraction and scanning electron microscopy and so on.The photocataiytic activities of TiO_2 films were investigated by the degradation of formaldehyde.The results indicate that the TiO_2 films in TiO_2/sepiolite composite powder calcined at 650℃ are anatase.The degradation effect of the composite powder for formaldehyde is good.
