Metal-organic framework templates and hosts of nanocatalysts

When: 25 October 2021, 15:00 GMT

Metal-organic framework templates and hosts of nanocatalysts: geometry, surface chemistry and performance webinar with Dr Petra Ágota Szilágyi (Queen Mary University of London).

Metal-organic frameworks (MOFs) are a unique class of materials in terms of the tuneability of their pore geometry, chemistry, and flexibility, which makes them desirable from fundamental and application viewpoints. Furthermore, the size regime of the typical MOF pores (ca. 0.5-3 nm) coincides with size ranges in which other interesting physical phenomena take place, which makes their pores desirable hosts for catalytically active particles with possibilities to tune their physical and, particularly, chemical properties.

Using a number of MOF-metal host-guest composites, I will discuss strategies for their synthesis and characterisation [1,2]. I will review the effect of pore size and functionalities on the ability of the frameworks to incorporate, control the geometry of, and interact with the guest particles [1-5]. Finally, I will use some examples to showcase how all of the above effects contribute to the catalytic performance of these host-guest composite materials in selected reactions, including the direct conversion of CO2 with H2 [6] and other important reactions.

Dr Petra Ágota Szilágyi is a Senior Lecturer in Functional Materials heading the Advanced Functional Hybrid Materials research group at the Queen Mary University of London. Having worked in France, the Netherlands, Australia and the UK, with a few months’ stunts in the USA and Japan, she has significant international and multidisciplinary experience in the broader field of materials science and technology. Her research interest is focussed on the sustainable production of metal-organic frameworks and their exploitation for energy- and environmental applications, particularly as tailor-made heterogeneous catalysts. She is recipient of the Top50 Women in Engineering: Sustainability Award (2020) and she has been visiting professor at the University of Artois (France) and the Advanced National Institute for Science and Technology (Japan). Dr Szilágyi is a keen science communicator, for which she has previously obtained the Media Fellowship of the British Science Association (2016).
