Greener manufacture of metal-organic frameworks

Metal-organic frameworks (MOFs) are a class of highly porous adsorbent materials that have promising applications in catalysis, gas storage, and gas separation. However, their manufacture often generates large volumes of toxic waste and uses large amounts of energy. Acsynam’s innovative supercritical CO2 technology not only enables the rapid, cost-effective synthesis of high-quality, high-porosity MOFs, but also does so in a clean, sustainable and environmentally- friendly manner. This is achieved by virtually eliminating the high volumes of solvents and corrosive reagents usually necessary for the manufacture of MOFs.

The technology uses supercritical carbon dioxide (scCO2) to afford the rapid, high-yielding manufacture of highly microporous metal-organic materials. The process uses benign, non-hazardous metal oxide feedstocks instead of corrosive metal salts and virtually eliminates the use of conventional organic solvents, resulting in a more cost-effective, sustainable, and environmentally- friendly process. The technology additionally provides a use for waste CO2streams, which can be recycled for re-use. The technology is easily adaptable and optimizable to the production of MOF materials incorporating a wide range of chemical building blocks, making the manufacture of any commercially-relevant MOF more efficient and economically accessible to our clients.

Key Features:

• MOFs are highly attractive for many industrial applications.

• Uses non-hazardous feedstocks.

• Cost effective and environmentally friendly.
