Abstract

In this work, catalysts were synthesized based on chemically modified clays through pillaring process with Al (III) and Fe (III) using commercial bentonite and acid-treated montomorillonite like KSF montmorillonite and K10 montmorillonite from Aldrich, as raw materials. The raw materials and chemically modified clays were characterized by: BET (Brunauer-Emmet-Teller) method and XRD (X-ray diffraction). Afterwards these catalysts were tested during wet oxidation with peroxides using phenol as target compound. Experimental results show that chemically modified clays with Fe(III) presented a higher catalytic activity in Fenton like processes than Al-Fe clays.
