摘要：

In this study, we describe the creation of linked semiconductor nanomaterials, which represents a significant development for photocatalytic applications. A Bi2O3-ZnO hetrostructured thin film was created using the SILAR-CBD deposition technique. In comparison to pure ZnO and Bi2O3, the produced heterostructured thin film showed greater photocatalytic (PCD) activity for the degradation of methylene blue (MB) dye under UV light. The formation of Bi2O3 (monoclinic lattice phase) and ZnO (hexagonal wurtzite phase) are the heterostructured nanomaterials that were generated, according to a powder XRD inspection. An image taken with HR-TEM demonstrates the mixing of nanoparticles and nanorod formations in the Bi2O3/ZnO. The vectorial movement of electrons (e-) and holes (h+) between ZnO and Bi2O3 is responsible for the boosted photocatalytic efficiency, which is in turn, accountable for the enhanced photocatalytic activities.
