The Correlation Between Structure and Photocatalytic Activity of ZnO Particles Prepared by Mild Wet Chemical Method

Abstract

Flower-like and roughly spherical ZnO nanocrystalline have been successfully synthesized through mild wet chemical method. The photocatalytic activities of the prepared photocatalysts were evaluated by degradation of rhodamine B (RhB) and phenol under UV light irradiation. Remarkably, the roughly spherical ZnO powder via homogeneous precipitation method exhibited superior photocatalytic performance and better photo-stability than that of flower-like ZnO substrate by hydrothermal synthesis way. The enhanced photocatalytic properties could be attributed to more active catalytic sites and superior charges separation efficiency.
