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.
