Reaction conditions strongly influenced reduction efficiency, with optimal performance at pH 6, a catalyst dosage of 2.5 g\u00b7L\n                    <jats:sup>\u22121<\/jats:sup>\n                    , and a short reaction time of 20 min. The enhanced catalytic performance under mild, environmentally friendly conditions highlights CuO\u2019s 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.
