The synthesis of nearly all industrial chemicals involves some sort of catalyst. MOFs are promising materials for heterogeneous catalysis (where the catalyst is in a different phase to the reactants) and our research team is investigating how particular structural motifs can be incorporated into the design of MOFs to develop new or more efficient catalysts. This work extends from garnering new fundamental insight into MOF supported catalysts through to making new MOF catalysts. Techniques such as post-synthetic metalation (see our review of this area) are important to preparing catalysts and we have also developed purpose-built catalytic testing facilities for examining gas phase catalysis. Some projects include:
- The development of a new group of azolium-containing materials that are important precursors to N-heterocyclic carbene (NHC) containing metal-organic frameworks (MOFs) with catalytic potential is a significant personal contribution. One of these NHC-MOFs is used to catalyse the hydroboration of CO2. See: A 3-D diamondoid MOF catalyst based on in situ generated [Cu(L)2] N-heterocyclic carbene (NHC) linkers: hydroboration of CO₂, Chemical Communications, 2014, 50, 11760-11763.
- Using a unique framework material prepared at the UoA we have been able to show by SCXRD the products of consecutive metalation and oxidative addition steps for a Rh(I) precursor and in recent work we have obtained X-ray crystallographic ‘snapshots’ of all the intermediates in the methanol carbonylation cycle (the Monsanto process) for a modified catalyst. For example: Mapping-out catalytic processes in a metal-organic framework with single-crystal X-ray crystallography, Angewandte Chemie - International Edition, 2017, 56, 8412-8416.
- Investigating how post-synthetically metalated MOF structures can be used as sacrificial templates to synthesise efficient catalysts for hydrogen conversion into suitable carrier gases for hydrogen transport, including methane and ammonia. See for example: Highly active catalyst for CO2 methanation derived from a metal organic framework template. Journal of Materials Chemistry A, 2017, 5, 12990-12997.
Biomolecule Protection in MOF biocomposites
Another research area utilises MOFs to protect biomolecules from inhospitable conditions. This processes, coined biomimetic mineralisation, is a rapid, easy to use coating procedure that uses the biomolecule to seed growth of a protective coating. This approach has been used to protect enzymes from harsh environments within a biomimetically mineralised MOF coating. In the past 2 years we have established a robust protocol for this chemistry, demonstrated the importance of protein surface chemistry and charge, and identified that the hydrophilicity of the MOF coating is essential for activity.

Gas storage and separations
Gas separations are important in clean energy technologies or in the separation of chemical feedstocks. Examples of our research activity is the design of a MOF that is flexible in the 'as-synthesised' form but upon activation – the process of desolvation that yields the adsorbing material – converts to a rigid 3D material. This material has the second highest CO2/N2 separation performance of any MOF material. See: Post-synthetic structural processing in a metal-organic framework material as a mechanism for exceptional CO₂/N₂ selectivity, Journal of the American Chemical Society, 2013, 135, 10441-10448.
Collaborative research with CSIRO on incorporation of molecular porous materials into mixed matrix membranes is another area of activity and two invited reviews on this topic have been published recently. See:
- AIMs: a new strategy to control physical aging and gas transport in mixed-matrix membranes. Journal of Materials Chemistry A, 2015, 3, 15241-15247.

Synthesis and characterisation of porous materials
A significant part of my research focuses on the synthesis and characterisation of porous materials. These contributions include: the synthesis of flexible MOF materials, novel solution-processable porous materials, and MOFs that enable structural characterisation of 'guest' metal complexes by single crystal X-ray crystallography. This experimental activity relies heavily on our in-house X-ray diffraction facilities for small molecule X-ray crystallography and powder X-ray diffraction.
- We have developed and exploited a "controlled flexibility hinge" design for MOFs that facilitate dynamic structural behaviour in the solid-state.

- Solution-processable porous materials such as porous organic cages and metal-organic polyhedra are among research targets within our research laboratory. These are examples of novel porous materials with potential applications in gas storage, separations and catalysis.

- A third major contribution is the study of reactions products and chemical reactivity within the chemically and spatially confined environment of a metal-organic framework.

For MOFs to be applied as components of real-world systems, precise control over and optimisation of the physical form of the material is required. In this respect we are examining modulation of the crystal size and morphology (changes at the nanoscale) and how the application dictates the internal organisation of the solid and overall external shape of the composite (changes at the macroscale). This work is done in collaboration with Dr Kenji Sumida (ARC DECRA fellow, School of Physical Sciences, UoA).

This research will advance the fundamental chemical science required for the emerging field of Metal-organic Framework (MOF) biocomposites. A significant challenge to the commercial use of enzymes (biocatalysis), proteins (protein-based therapeutics) and virus-based vaccines is their instability to elevated temperatures and/or non-biological media. MOFs can encapsulate and protect biomolecules, thereby overcoming this limitation. This project will develop fundamental parameters that govern the formation, stability and activity of these biocomposites, expanding the scope of MOF materials available for bioprotection, and enable new developments in the areas of industrial biocatalysis and protein/virus-based therapeutics.
Prof. Christian Doonan; Prof. Christopher Sumby; Dr Kenji Sumida, Examining small molecule activation in metal-organic framework pores. ARC DP190101402
This project aims to uncover important chemical knowledge regarding small molecule activation by reactive metal species that are site-isolated and stabilised within the pores of metal-organic frameworks. These insights will lead to the development of new materials that are able to activate small molecules, such as carbon dioxide and methane, and facilitate their conversion to commodity chemicals and fuels. Uncovering energy-efficient strategies for valorising abundant small molecules is a key challenge for future energy sustainability. The outcomes of this project will inform the design of the next-generation catalysts for conversion of methane to methanol, a potential fuel, and facilitate the transition to a clean energy future.

Project Summary: This project aims to understand the chemistry that governs the crystallisation of metal-organic frameworks (MOF) around functional biomacromolecules and explore these bio-composites’ uses. Functional biomacromolecules, such as proteins, could be applied to biotechnology and Industrial biocatalysis. The project will develop MOF-encapsulated biocatalytic platform materials that allow inherently fragile biomacromolecules to remain active in conditions needed for industrial processes. This project could advance the widespread commercial application of biocatalysts and biosensors.

Project summary: The aim of this project is to unearth structural insights into the chemistry of coordinatively unsaturated metal complexes – reactive species lacking their full complement of binding groups – by isolating them within a carefully designed metal-organic framework and examining them via single crystal X-ray diffraction. Such intrinsically reactive species play an important role in metal-based catalysis, but their definitive structural characterisation remains a significant challenge. This project aims to facilitate a detailed understanding of how these species bind and activate substrates and thus provide important first steps towards developing novel adsorbents for separations and efficient catalysts.
