Previous: Dual function materials (DFMs) for integrated CO2 direct air capture and catalytic conversion to sustainable hydrocarbons

The DFM is composed of a CO2 sorbent, CO2 conversion catalyst, intimately dispersed on a high surface area carrier, all of which are deposited on a monolithic support,  Due to the close proximity of catalyst and sorbent on the material surface, the DFM is unique in its ability to capture CO2 and catalytically convert it in situ upon the addition of renewable (“green”) H2. Therefore, a DFM reactor can streamline the CO2 capture and upgrading processes, which is a critical challenge for scientists and engineers at the forefront of sustainable engineering.

The DFM is composed of an inorganic alkaline selective CO2 sorbent and CO2 conversion catalyst, all nano-dispersed on a high surface area carrier. These composites are deposited on the walls of monolithic structures for reduced pressure drop required to process large amount of air with dilute concentrations of CO2.  The nano-properties result in unique performance and stability. Due to the close proximity of the catalyst and sorbent on the material surface, the DFM is unique for its ability to capture CO2 and catalytically convert it in situ upon the addition of “green” renewable H2.
