Abstract

Semiconductor material as a heterogeneous photocatalyst offers certain advantages, such as fast degradation and mineralization of organic pollutants. However, the degradation of organic dyes is still restricted by challenges, including the limited photocatalytic activity under visible light. To overcome this challenge, a visible-light-driven ZnO/ZnS/MnO₂ ternary composite was developed through a co-precipitation route and utilized for photocatalytic degradation of methylene blue. The XRD, FTIR, SEM–EDS, and UV–Vis analyses confirmed the successful development of photocatalyst. The ZnO/ZnS/MnO₂ nanocomposite exhibited 97% photocatalytic degradation efficiency for methylene blue under visible light.
