Abstract

Amine functional solid sorbents for carbon dioxide capture and sequestration may be prepared from metal oxide foam solid sorbent supports by treating an appropriate metal oxide foam solid sorbent support with an amine material. Desirable are metal oxide foam solid sorbent supports with a foam structure and morphology at least substantially absent hollow sphere, layered sphere, wormlike and amorphous structure and morphology components. The amine materials may be sorbed into the metal oxide foam solid sorbent support, or alternatively chemically bonded, such as but not limited to covalently bonded, to the metal oxide foam solid sorbent support.
