Preparation, characterizations and its application of heterogeneous Fenton catalyst for the treatment of synthetic phenol solution

Fe-Co-Al trimetal oxide (TMO) was prepared by the sol-gel route for the oxidation of phenol solution by catalytic wet peroxide oxidation (CWPO) method. The characteristic of Fe-Co-Al was carried out. The size of the catalyst was found to be between 1 and 5 mu m with good porosity which was confirmed using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and N-2 adsorption-desorption isotherms. The catalytic activity results showed almost complete oxidation of phenol up to 1000 mg/L. The oxidation process and the products formed were confirmed using various instrumental analyses. The TMO catalyst could be reused even after three cycles very effectively. (C) 2012 Elsevier B.V. All rights reserved.
