Consolidation of tin sulfide chalcogels and xerogels with and without adsorbed iodine
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 …
