ZnFe۲O۴@Co۳O۴/X zeolite: A novel magnetic recoverable nanocomposite for the sonocatalytic degradation of rhodamine B (RhB) dye

Highly efficient and effective remediation of toxic organic dye sewages are a major dilemma in the industries. In this work, the novel ZnFe۲O۴@Co۳O۴/X zeolite nanocomposite was successfully fabricated and applied for the rhodamine B (RhB) dye in water media. The as-fabricated ZnFe۲O۴@Co۳O۴/X zeolite nanocomposite was identified via FESEM, EDAX, FTIR, XRD and VSM analyses. Several parameters such as irradiation time, initial dye concentration, process type, catalyst dosage, organic dye and type H۲O۲ concentration have been evaluated to attain the maximum sonocatalytic efficiency. Regarding the obtained results, the ZnFe۲O۴@Co۳O۴/X zeolite sonocatalyst was incredibly able to completely degrade this dye by the ultrasonic and H۲O۲. The free .OH radicals were recognized as the main active species on the RhB degradation under US irradiation. Additionally, the reproducibility of the ZnFe۲O۴@Co۳O۴/X sonocatalyst was investigated, which affirmed that it can be reused up to four runs with almost trivial loss of catalytic activity. Additionally, the sonodegradation of RhB by the ZnFe۲O۴@Co۳O۴/X zeolite sonocatalyst in the presence of US/H۲O۲ system reveals a great activity to investigate highly removal of organic contaminants from wastewater
