Mesoporous Silicoaluminum Pillared Clays with High Thermal Stability and Brφnsted/Lewis Acidity by One-pot Synthesis

Mesoporous silicoaluminum pillared clays have been synthesized by one-pot gallery-templated synthesis using organomontmorillonite, tetraethyl orthosilicate and alumina isopropoxide as precursor. According to the characterization by powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), N...

Summary:Mesoporous silicoaluminum pillared clays have been synthesized by one-pot gallery-templated synthesis using organomontmorillonite, tetraethyl orthosilicate and alumina isopropoxide as precursor. According to the characterization by powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), N2 adsorption isotherms and pyridine adsorption infrared (IR) techniques, the synthetic silicoaluminum pillared clays possess regular porosity with high thermal stability up to 750 ℃ and Brφnsted/Lewis acidity.
