Cucurbituril-polyethylenimine-silica complex, preparation method thereof and carbon dioxide asorbent comprising the same

摘要

The present invention relates to a cucurbituryl-polyethyleneimine-silica complex, a method of manufacturing the same, and a carbon dioxide adsorbent comprising the same, and more specifically, to form a complex in which cucurbituril and polyethyleneimine are combined, and supporting the cucurbituril-polyethyleneimine by supporting it in silica. -Silica composites can be prepared and used as carbon dioxide adsorbents with thermal stability and urea formation suppressed.
