Multifunctional ZnO Nanomaterials with Broad-Spectrum Defect-State Absorption for Enhancing the Photocatalytic Degradation of Organic Dyes

inhibited the degradation of MB and RhB, it promoted the decomposition of MO. Furthermore, the ZnO NFs exhibited excellent recyclability in five consecutive degradation cycles. The self-synthesized ZnO nanomaterials in this study, with their broad-spectrum absorption, high stability, and eco-friendly properties, demonstrate their potential as an efficient and low-cost photocatalyst for large-scale wastewater treatment.
