Nickel-Modified Bifunctional MOF-on-MOF Systems for Upgrading Sequestered CO2

Project description

Engineering a single system for carbon capture and conversion

Capture and conversion technologies are essential for reducing carbon emissions. However, their widespread adoption in industry is challenged by technical and economic obstacles, such as high energy consumption, poor performance, and lack of integrated capture and conversion processes. Supported by the Marie Skłodowska-Curie Actions programme, the NIMBUS project aims to address these challenges by developing a sustainable process that simultaneously captures and converts CO2 into useful products such as methane. Leveraging the properties of nickel-based metal-organic frameworks (MOF), it will engineer hierarchical MOF-on-MOF structures with multiple functionalities. By integrating metal doping, defect-functionalisation and core-shell structures, NIMBUS will transform CO2 waste into valuable resources, promoting a circular carbon economy.

Objective

The increasing climate crisis demands urgent advancements in carbon capture and conversion (CCC) technologies to mitigate rising atmospheric CO2 levels. Current methods face critical limitations, including high energy demands, poor performance under realistic conditions, and a lack of integration between CO2 capture and catalytic advancement. This project, Nickel-Modified Bifunctional MOF-on-MOF Systems for Upgrading Sequestered CO2 (NIMBUS), aims to overcome current limitations by taking advantage of the remarkable properties of metal-organic frameworks (MOFs), such as their porosity, outstanding mechanical stability, chemical versatility, and reactivity. The strategy involves the rational design of a novel MOF-on-MOF core-shell architecture, by synergistically combining three widely single-optimized approaches: (1) enhanced CO2 uptake through metal doping and defect-functionalisation, (2) humidity resistance via a hydrophobic shell, and (3) catalytic conversion to valuable-added products using embedded Ni nanoparticles. Thanks to the integrations of these functionalities into a single material, NIMBUS aims to achieve a significant increase in CO2 adsorption and selectivity for CH₄ production under industrial flue gas conditions (60% RH, 40–120°C). The project employs advanced characterization techniques, including synchrotron-based analysis to establish structure-property relationships and optimize material performance, enabling the rational design of robust CCC materials. By combining defect-functionalisation, metal doping, and core-shell assembly, NIMBUS aims to create a sustainable pathway toward a circular carbon economy, aligning with global climate goals by converting CO2 from a waste product into a renewable resource.
