The activation of heterogeneous Fenton-type catalyst Fe-MFI

The activation of iron-containing zeolite of MFI structure with mineral and carboxylic acids in heterogeneous Fenton reaction was experimentally studied. The catalytic activity of the zeolite was tested in the hydrogen peroxide decomposition reaction. The activation effect of acids was observed in the following decreasing order: oxalic > acetic > hydrochloric > formic. The catalyst pre-treatment with nitric acid was ineffective. Optimum conditions for the most effective pre-treatment of the zeolite with aqueous oxalic acid solutions were established. (c) 2007 Elsevier B.V. All rights reserved.
