Abstract

The ZnO:CuO nanocomposite photocatalytic activity was experimentally and numerically investigated. This nanocomposite exhibits stability and durability during photodegradation. The nanocomposite with a ZnO/CuO ratio of 2.0 synthesized by microwave-assisted hydrothermal at 70 °C in 10 minutes exhibits a photocurrent density of over 1.0 mA.cm⁻² for the ZnO layer and an optimal degradation efficiency of 86.4 %. The photocatalytic efficacy of the ZnO:CuO nanocomposite depends on the current generated by ZnO rather than the total density of photo-induced current. This nanocomposite can be a promising photocatalyst because of its enhanced light absorption and effective suppression of photogenerated electron-hole pair recombination.
