About the Project
Metal–organic frameworks (MOF) materials are constructed from metal nodes bridged by organic ligands to form porous three-dimensional networks that can accommodate a range of ions and substrates. Their pore chemistry, charge, defects and flexibility can be controlled with chemical precision, giving direct control over the capture and binding of confined substrates. We have developed a range of materials that are highly stable towards the capture of CO2 and NOx substrates, and this offer a unique…
opportunity to design new porous photocatalysts. The high crystallinity and long-range order of MOFs enable the advanced characterisation of host-guest interactions, structures and of intermediates to give understanding at the molecular level.
This interdisciplinary project brings together two groups with established expertise in catalysis (Chris Hardacre) and materials synthesis and characterisation (Martin Schröder) to develop MOFs as reductive photocatalysts for conversion of CO2 to C2+ products and NOx to N2. Previous collaborative work has confirmed the use of non-thermal plasma for reduction of NO2 using a Cu-doped MOF (J. Am. Chem. Soc., 2021, 143, 10977−10985; Cell Reports Physical Science, 2021, 2, 100349) and conversion of methane to acetylene and ethylene (J. Am. Chem. Soc., 2023, 145, 20792-20800). We have also established the activity of MOFs for photo-reduction of CO2 (J. Am. Chem. Soc., 2026, 148, 11749-11757). This proposal will use modulation excitation, recently developed by Hardacre (Angew. Chem. Int. Ed., 2024, 61, e202401888), to study the formation and nature of key intermediates. Modulation excitation is especially sensitive and can detect and measure changes at fractions as low as 2% of the total number of electroactive species. Thus, modulating the photoexcitation will enable measurements on intermediate species by X-ray adsorption and IR spectroscopy.
We will focus on the photoactivation of (i) saturated systems to generate dynamic and transient open metal sites for catalysis (eg MFM-series of materials), (ii) doped MOFs in which active metal sites can be generated at fixed positions, and (iii) defect MOFs in which linkers are missing to generate unsaturated active sites.
The project will give the student excellent training in photocatalysis and the measurements of catalytic activity and their intermediates (led by Hardacre) as well as the design, synthesis and characterisation of inorganic/organic materials and host-guest interactions (led by Schröder). This will include experiments and characterisation at National Facilities for diffraction, scattering, imaging and spectroscopic studies, particularly using excitation modulation. The ambition is to develop and understand the activity of new photochemical catalysts based upon MOFs.
This project is expected to start in September 2027.
