Abstract

Using ethylene glycol derivatives of aluminium isopropoxide and ethyl orthosilicate precursors in the sol-gel process, discrete aluminosilicate nanoparticles were produced that had a strong Brönsted acidity, high surface area and high thermal stability; these properties were ascribed to a high dispersion of the aluminium atoms in the silica matrix.
