Abstract
Solid sorbent materials have been prepared by combining polyethyleneimine (PEI) with silica precursors. The solid sorbent materials can be used, for example, for acid gas separation, gas purification, and water purification applications. Advantageously, such materials can be water stable and the capacity of such solid sorbent materials does not diminish substantially after repeated use and regeneration.
