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

摘要

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 μm 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.
