摘要

过渡双金属氧化物催化剂能够活化过一硫酸盐(PMS),产生氧化活性基团,促进室温反应,而且成本相对较低。我们成功地利用冷冻干燥法获得了 CuFe2O4,以促进过一硫酸盐的活化,从而降解罗丹明-B 染料。催化剂通过 XRD 和 SEM 进行了表征。研究了各种反应参数(如初始 pH 值和 PMS 用量)对罗丹明-B 降解的影响。结果表明,以冷冻干燥法为沉淀剂制备的 CuFe2O4 催化剂颗粒均匀规整、结晶度高、纯度高、比表面积大、不含杂质官能团。此外,制备的 CuFe2O4 材料还具有更高的催化性能。在催化过程中,罗丹明-B 的浓度设定为 20 mg-L-1,CuFe2O4 材料的用量为 200 mg-L-1。最佳 pH 值为 9.0,理想的 PMS 浓度为 1.0 mmol-L-1。在这些特定条件下,仅用了 27 分钟的催化时间,罗丹明-B 的降解率就达到了惊人的 99%。

Preparation of CuFe2O4 via freeze-drying method and its application in boosting peroxymonosulfate activation to degrade rhodamine-B dye

The transition bimetallic oxide catalyst demonstrates the ability to activate peroxymonosulfate (PMS), generating oxidative active groups and facilitating room temperature reactions, all at a relatively low cost. The freeze-drying method was successfully utilized to obtain CuFe2O4 to boost peroxymonosulfate activation to degrade rhodamine-B dye. The catalyst underwent characterization through XRD and SEM. The impact of various reaction parameters, such as initial pH value and PMS dosage on the degradation of rhodamine-B, was examined. The results revealed that the CuFe2O4 catalyst obtained via freeze-drying method as the precipitant exhibited uniform and regular particle characteristics, remarkable crystallization degree, high purity, enormous specific surface area, and an absence of impurity functional groups. Additionally, the prepared CuFe2O4 material showcased enhanced catalytic performance. To carry out the catalysis process, the rhodamine-B concentration was set at 20 mg·L−1, with an amount of 200 mg·L−1 of CuFe2O4 material used. The optimal pH was determined to be 9.0, while the ideal PMS concentration was found to be 1.0 mmol·L−1. Under these specific conditions, an impressive 99% degradation rate of rhodamine-B was achieved in just 27 min of catalysis.

期刊介绍: Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
