  "abstract": "In this study, a CuO/ZnFe₂O₄ heterostructure in the form of a flower, consisting of rod-like surface features associated with CuO on ZnFe₂O₄ microspheres, was successfully synthesized and evaluated for its catalytic reduction of chloramphenicol (CAP) in the presence of NaBH₄. Structural and morphological analysis confirmed the successful formation of the heterostructure with enhanced contact between ZnFe₂O₄ and CuO. Compared to pure ZnFe₂O₄, the CuO/ZnFe₂O₄ catalyst exhibited significantly improved catalytic activity for CAP reduction. Reaction conditions strongly influenced reduction efficiency, with optimal performance at pH 6, a catalyst dosage of 2.5 g·L⁻¹, and a short reaction time of 20 min. The enhanced catalytic performance under mild, environmentally friendly conditions highlights CuO's crucial role in promoting surface electron transfer and facilitating reduction. Kinetic analysis at room temperature indicated a change in apparent kinetic behavior during the reaction, with pseudo-first-order behavior in the initial stage and a tendency toward zeroth-order behavior at later times. This evolution is consistent with the involvement of surface-mediated catalytic processes. Overall, the CuO/ZnFe₂O₄ heterostructure shows significant potential as an efficient catalyst for rapid CAP reduction under near-neutral conditions, offering a promising strategy for wastewater treatment.",
