摘要:

采用乳化溶剂蒸发的方法制备了负载型催化剂环多胺锰/乙基纤维素微胶囊(MnAcL-EC), 并确认了MnAcL在微胶囊内负载后结构的完整性, 对其进行了形貌结构表征, MnAcL-EC微胶囊负载型催化剂内部呈特殊的多芯结构. 该催化剂在活性蓝(C.I. Reactive Blue 49)的氧化反应中表现出了优异的催化性能. 催化反应后微胶囊粒径增大, 球体表面孔道增多; 元素分析结果显示, 微胶囊内负载的MnAcL在催化反应后几乎没有减少, 表明负载后的MnAcL是在微胶囊内部催化了外界底物分子的氧化反应. 所制备的MnAcL-EC微胶囊具备很好的循环利用性, 可以有效减少催化活性组分的流失, 方便回收利用.

Abstract:

Manganese complex of cyclic polyamine(MnAcL) was encapsulated within ethyl cellulose(EC) microcapsules via emulsion solvent evaporation technique. The morphology of MnAcL-EC microcapsule was characterized. The results of UV-Vis confirmed the structural integrity of MnAcL in EC microcapsules. The catalytic property of the as-prepared MnAcL-EC microcapsules was evaluated by the oxidation of C.I. Reactive blue 49 with H2O2. It was found that both the particle size and the pores on the surface of the spheres increased after the reaction. However, the amount of MnAcL in EC microcapsules was almost not changed, as measured by the elemental analysis. It was suggested that the oxidation of C.I. Reactive blue 49 was catalyzed successfully by the encapsulated MnAcL inside the microcapsules. What’s more, the as-prepared MnAcL-EC microcapsules could be reused for at least 4 times. These results demonstrated that the MnAcL-EC microcapsule prepared in this paper could be applied as a high efficient catalyst.
