실험 절차

A silicalite-titania-silica hybrid membrane was prepared using the sol gel technique and suction method as follows. A silicalite-impregnated substrate was prepared as in Example 1. 0.4903 g H2O and 0.0789 g HCl (37% aqueous solution) were diluted in 9.000 g of anhydrous isopropanol. 2.5560 g of titanium tetraisopropoxide and 0.2080 g of silicon tetraethoxide were added to 9.0000 g of anhydrous isopropanol. The H2O--HCl-iPrOH solution was added slowly to the Ti(OiPr)4 --Si(OEt)4 -isopropanol solution with a magnetic stirrer to yield a titania-silica hybrid sol. A silicalite-titania-silica hybrid membrane was formed using the sol and the method of Example 1.
