Title: Consolidation of tin sulfide chalcogels and xerogels with and without adsorbed iodine

Abstract

Tin sulfide (Sn2S3) chalcogels are one of the most effective non-oxide 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. The system with both iodine-sorbed and iodine-free Sn2S3 chalcogels provides better glass-forming characteristics 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 also conducted using microwave sintering and hot isostatic pressing with Sn2S3 xerogels.
