Hierarchical Porous Covalent Organic Nanosheets and Nanosheets Based Hybrid Membranes for Carbon Capture and Separation of CO2

Subcategory (under Clean Energy): Carbon Capture
Technology Readiness Level (TRL): 3-4- Early prototype
Technology Outline (Process Description)

In this project, initially team has demonstrated a simple strategy of interfacial layer-grafting to fabricate asymmetric COF- graphene Janus thin-films. The judicious choice of 2D graphene sheets as a grafter furnished us to leverage such assembly via the non-covalent interactions between the asymmetric layers (COF and graphene), rendering flexible Janus films at the DCM- water interface. Two self-standing porous COF-graphene Janus thin films with thicknesses ~2-5 μm have been synthesized following the protocol.

Salient Features/Advantages

  • The incorporation of other electrochemically active flexible 2D materials like 2D carbides and nitrides (MXenes) via different supramolecular or intermolecular interaction includes more flexibility and electrochemical efficiency in term of performance
  • To achieve significant CO2 adsorption capacity of a two-dimensional COF via channel wall functionalization
  • High adsorption selectivity of the material for CO2/N2 flue gas mixture

Key Outcomes

  • The project team has synthesized hierarchical covalent organic nanosheets and nanosheets based hybrid membranes for effective and selective CO2 capture.
