Silica pillared clays with large interlayer distance were synthesized by the simultaneous intercalation of 3-aminopropyltriethoxysilane (APS) and polyvinyl alcohol (PVA). Characterization of the synthetic silica pillared clay was done by X-ray diffraction measurement, nitrogen adsorption-desorption measurement and X-ray fluorescence analysis. The gallery height of the synthesized pillared clay was 1.3nm in the presence of PVA, and it was found that the gallery height was twice as large as that of the pillared clay synthesized without using PVA. The specific surface area and pore volume of the pillared clay obtained with PVA were larger than those obtained without PVA. It was confirmed that the interlayer distance was enlarged with increase in the amount of pillaring precursors only by using PVA.
