Mixed (Al-Fe) pillared clays are very efficient solid catalysts for oxidation of organic compounds in water by hydrogen peroxide. We have shown that in rather mild experimental conditions (atmospheric pressure, T less than or equal to 70 degrees C) and with a low excess (20%) of hydrogen peroxide, phenol was rapidly converted, mainly to CO without significant catalyst leaching, The (Al-Fe) pillared clay catalyst (called FAZA) can be used several times without any change of its catalytic properties. According to the low leaching observed and a previous Mossbauer spectroscopy study, the iron species appear to be strongly bonded to the aluminium pillars,
