利用酸性催化TEOS水解進(jìn)行SiO2包覆實驗
|
新手,想利用SiO2包覆做成納米粒子,但不知道怎么控制條件,follow的下面這篇文獻(xiàn)(dx.doi.org/10.1021/ja3003638 | J. Am. Chem. Soc. 2012, 134, 5390−5397),總是做不出來![]() 請問這個酸度多少比較合適? 需要控制溫度嗎? 反應(yīng)完全后應(yīng)該是透明澄清的液體? 是不是有什么需要注意的地方?或者有更好的方法嗎? In a 20 mL glass scintillation vial, 2.0 g of Pluronic F127, 1.0 mg (1.56 × 10−6 mol) of PdOEP, and 10 mg (3.03 × 10−5 mol) DPA were carefully soluble in toluene. The solvent was evaporated from the homogeneous lavender organic solution by means of a gently nitrogen flow and subsequently under vacuum. The solid residue was then dissolved under magnetic stirring with 100 mL of HCl (0.85 mol L−1). TEOS (2 mL) was then added to the resulting aqueous solution followed by DEDMS (450 μL, 2.1 mmol) after 6 h. The mixture was kept under stirring for 48 h at 25 °C before dialysis/ultrafiltration treatments and measurements. |
