ZnO nanowires and nanorods based ZnO/WO3/Pt heterojunction for efficient photocatalytic degradation of estriol (E3) hormone

Abstract

In this report, ZnO nanowires and nanorods based ZnO/WO3/Pt heterojunction were successfully prepared on a glass substrates via a facile hydrothermal growth method followed by spraying. The photocatalytic performance was evaluated by the degradation of estriol (E3) hormone under UV light irradiation (~365 nm) in a closed continuous flow reactor. The as-prepared samples achieved an excellent photodegradation rate in the range of 23-37% and 63-86% for the nanorods and nanowires morphology, respectively. This article provides a new insight into the construction of suitable geometrically optimized heterojunction for the remediation of persistent bio toxicants.
