Abstract
Tin sulfide (Sn2S3) chalcogels are one of the most effective nonoxide aerogels evaluated to date for iodine gas capture. This is attributed to the fact that the Sn within the gel network has a strong affinity for chemisorption of iodine to form SnI4. This study demonstrates an approach for consolidating the raw and iodine-sorbed Sn2S3 chalcogels into a chalcogenide glass using GeS2 as a glass-forming additive. Adding GeS2 to iodine-sorbed or iodine-free Sn2S3 chalcogels provides better glass formation than Sn-S or Sn-S-I alone, and the quantity of iodine measured in the bulk glass of the consolidated iodine-sorbed Sn2S3 chalcogel was at ∼45 mass%. Additional experiments were conducted using microwave sintering and hot isostatic pressing with iodine-sorbed Sn2S3 xerogels to evaluate alternative consolidation techniques.
