溶膠凝膠法用鈦酸四丁酯制備納米TiO2出現(xiàn)問題,跪求大家指教 已有6人參與
|
||
|
TiO2 sol was prepared at room temperature in the following way: 8.68 ml of tetrabutylorthotitanate was dissolved in the mixture solution of 35 ml of ethanol and 2.82 ml diethanolamine. After magnetic stirring for 2 h, the obtained solution was hydrolyzed by the addition of a mixture of 0.45 ml deionized water and 4.5 ml ethanol dropwise under magnetic stirring. After stirring for 2 h, the TiO2 sol was kept in a brown glass bottle to age for 24 h at room temperature. 按照上面文獻中的方法,只是把二乙醇胺換成了三乙醇胺,其他步驟都一樣,為啥24小時后還是淡黃色的溶液,沒有一點要變成溶膠的感覺,是我哪里弄錯了,還是文獻中省略了哪些關(guān)鍵步驟? 求大家批評指正(我準備把納米粒子溶膠添加到電鍍液中制備納米復(fù)合鍍層,如果大家有其他好的方法也可以提出,必有重謝 ,我的金幣還是不少的哦,哈哈 ) |

如果用乙醇胺的話或許結(jié)果會好看點,三乙醇胺堿性比較弱,或許延長時間或者升高溫度會有點效果吧; 參見以前討論http://www.gaoyang168.com/html/201203/4264155.html |
