Abstract
The photocatalytic degradation of Ciprofloxacin (CIP) grows into a claim in terms of environmental remediation. Herein, we prepared ZnMn2O4-ZnO nanocomposite, which is a visible-light-responsive using the one-pot method. Adding 7% of ZnMn2O4 to ZnO leads to a contraction of the energy band gap of zinc oxide from 3.3 to 2.3 eV. 7% of ZnMn2O4-ZnO nanocomposite can degrade CIP completely within 30 min at 1.5 g/L using visible light illumination. The improvement of zinc oxide photocatalytic activity by coupling of ZnMn2O4 is due to avoid photogenerated charge carriers recombination and enlargement of visible light absorption. The study initiates the gate for the broad purpose of photocatalysts nanocomposite as a fiction useful material for CIP remediation using an exposure of visible light.
