Abstract

Many traditional photocatalytic materials such as ZnO and TiO2 are ultraviolet lighttriggered due to their wide band gap, however indoor light and sunlight reaching the surface of the earth are in the visible light region. This research aims to fabricate a photocatalytic material that can be triggered using visible light. Ceramic composites with ZnO and CuO interfaces were constructed using heterogeneous mixing technique. The photocatalytic activities of the samples were determined through their ability to degrade methyl orange dye under visible light illumination. Results show that the existence of the ZnO-CuO interface improved the visible light photocatalytic activity of the material.
