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.
