摘要 分别采用胶晶模板法和溶胶-凝胶法制备了具有三维有序大孔(3DOM)结构和无3DOM结构的铜硅复合物。通过静态实验评价了复合物对气态碘的吸附性能。采用SEM、TEM、XRD、热重仪对吸附碘前后的样品进行了表征,并对其进行了N2等温吸附脱附测试。结果表明:所制备的3DOM铜硅复合物三维孔道结构规整;与无3DOM结构的铜硅复合物及商品纳米铜粉相比,3DOM铜硅复合物对气态碘的吸附性能明显提升,这主要归功于其发达的孔道结构、大的比表面积和纳米尺寸晶粒。这一研究为开发新型高效的碘吸附剂提供了很有价值的依据。

Abstract: Copper-silica composites with/without three-dimensionally ordered macropores(3DOM) structure were synthesized by colloidal crystal template method and sol-gel method respectively. The performance of prepared samples for iodine vapor adsorption was evaluated by static testing, the samples before and after adsorption were characterized through SEM,TEM, XRD, TG-DTG, and the N2 isotherm adsorption desorption test was carried out. The results indicated that the structure of 3DOM copper-silica composites is intact, and the performance of 3DOM copper-si-lica composites was improved highly compared with copper-silica composites as well as the commercial nano-copper, this is mainly attributed to the unique structure of 3DOM: the develop pores, high surface areas and nano-sized crystal. This study provided significant results for development of new high performance iodine adsorbents.
