摘要：

High-surface-area pillared clays (PILC) were prepared from naturally occurring montmorillonites by exchanging interlayer ions to polyoxocations containing (i) aluminum (Al-13-PILC), (ii) iron adsorpted onto Al-13-PILC, and (iii) iron and aluminum located within the same complex (Fe0.8Al12.2-PILC. The obtained Fe0.8Al12.2-PILCs were characterized by DR-UV-vis and IR spectroscopy, XRD, ESR, scanning electron microscopy and low temperature N-2 adsorption measurements. Important factors affecting catalyst activity and phenol removal efficiencies have been studied, i.e. the effect of pH, temperature, catalyst concentration and stability of the catalyst.
