Synergistic Effects of Activated Carbon on Zno for Improved Photocatalytic Degradation of P-Nitrophenol

Abstract

Here, we report the synergistic effect of heterogeneous photocatalysis by combining ZnO and activated carbon (AC) composite (ZnO/AC) towards the remediation of water polluted with hazardous organic pollutant. ZnO/AC composites were prepared by simple and non-toxic method, without use of organic solvents. The prepared composite was characterized by XRD, SEM and BET. The photocatalytic activity was tested with photodegradation of p-Nitrophenol (PNP) under UV irradiation. The present investigation showed enhanced photocatalytic degradation efficiency of ZnO/AC over ZnO.
