摘要:
The invention relates to a method of preparing an adsorbent material on the basis of a porous metal-organic framework (MOF) being suitable for adsorbing gases, in particular carbon dioxide (CO 2 ), comprising the steps of (a) providing at least one porous metal-organic framework in particulate form; (b) providing graphene oxide (GO) in particulate form; and (c) combining the at least one porous particulate metal-organic framework with the particulate graphene oxide to obtain the adsorbent material. Moreover, the invention relates to an adsorbent material of the type as mentioned above as well as to the use of said adsorbent material in an adsorption process, in which the adsorbent material is exposed to a gas stream so as to adsorb a gas component of the gas stream, and in which the gas component is desorbed by heating the adsorbent material by means of exposing it to high-frequency electromagnetic radiation for regeneration.

The present invention belongs to the field of nanoporous materials, in particular metal organic frameworks (MOFs) and Lewis-based gas delivery and/or slow release, or the detection of Lewis-based gas(es) in gases or liquid streams. The present invention relates, inter alia, to a new ultra-microporous crystalline metal organic framework solid ( comprising bisphosphonic acid ligands (also refered to as Phosphonate MOF), such as MIP-210(M) and uses thereof as a carrier in Lewis-based gas (such as NO) delivery. The invention also relates to controlled release of the Lewis-based gas in wounds, for example by topical application. The invention also encompasses a synthetic method for producing the new ultra-microporous crystalline metal organic framework solid of the invention. The MOFs of the present invention can be used in various applications such as gas carrier and/or for the controlled release of gas. The MOFs of the present invention thus are very versatile and have therapeutic and non therapeutic applications.
