Catalytic wet peroxide oxidation of phenol wastewater over a novel Cu-ZSM-5 membrane catalyst

A novel Cu-ZSM-5 membrane catalyst was prepared and characterized for catalytic wet peroxide oxidation (CWPO) of phenol wastewater in a continuous reactor. The Cu-ZSM-5 membrane catalyst was first prepared by the secondary growth process and incipient wetness impregnation method, and then characterized by thermal gravimetric (TG) analysis, N-2 adsorption-desorption, X-ray diffraction (XRD), scanning electron microscopy (SEM) and H-2-temperature programmed reduction (H-2-TPR), respectively. This catalyst exhibited an excellent catalytic performance (complete phenol conversion and TOC conversion about 65% without toxic quinones detected). (C) 2015 Elsevier B.V. All rights reserved.
