摘要
The present invention provides a macroporous foam comprising microporous zeolite or zeotype material and preparation thereof, which comprises dipping a polymeric template capable of releasing an amine which has a sponge or macroporous structure and can be selected from a group consisting of polyurethane, polyamides, aromatic or aliphatic polyimides, polyamideimides, epoxy resins having an amine skeleton, and polymeric materials capable of releasing an organic amine by hydrolysis, in an alkaline or acidic solution, gel or sol of a precursor of said zeolite or zeotype material, and reacting the resultant at a suitable temperature for a period such that all or almost all of the polymeric template can be replaced with zeolite or zeotype material. Said foam comprising zeolite or zeotype material has the outer shape and size and the inner sponge or macroporous structure which are the same or similar to those of the polymeric template used.
