Project description
Characterising zeolites’ dynamical behaviour under operating conditions for catalysis
Carbon-rich organic matter and plastics have the potential to contribute to a circular economy, replacing conventionally used chemicals and fuels derived from fossil fuels with biomass and recycled plastics as feedstocks. Zeolites are important catalysts for some reactions involving organic molecules. They are widely used in chemical and fuel production and could potentially be used to exploit biomass and recycled plastics. However, they are challenged by the hot water conditions necessary to convert these novel feedstocks. The EU-funded ZEOLANDO project aims to characterise the dynamical behaviours of zeolite frameworks. Special attention will be paid to their active sites, when exposed to water under conditions relevant to catalysis combining experimental and computational approaches.
Objective
Biomass and plastic recycling feedstocks hold significant potential to replace chemicals and fuels derived from fossil resources. However, their distinct chemical compositions, and large water content, present challenges to existing infrastructure and catalysts. Zeolites, widely used in chemical and fuel production, face concerns regarding their stability under hot liquid water conditions relevant for converting these novel feedstocks. Thus, understanding the mechanisms behind zeolite deactivation/stabilization is essential. The ZEOLANDO project will use an integrated approach combining experimental and computational operando methods, including NMR and vibrational spectroscopies (IR and inelastic neutron scattering), as well as neural-network-accelerated atomistic simulations. The project objective is to investigate the spatiotemporal evolution of zeolite frameworks, elucidate the structure of active sites, and explore their deactivation when exposed to water under operando conditions, i.e. at temperature, pressure and surface coverage used in catalysis. This research represents a substantial advancement over static or short dynamical simulations and conventional experimental characterization studies, that often ignore the dynamical effects arising under operando conditions. My expertise in experimental characterization, particularly utilizing NMR and vibrational spectroscopies, combined with the host groups proficiency in advanced computational methods (including neural network potentials), uniquely positions ZEOLANDO to unveil the dynamic nature of the zeolite structure and acid site speciation under operando conditions, and can lead to the development of new and improved catalyst. By ensuring constant feedback between experimental and computational results, this project aims to enhance the understanding of zeolite behaviour during chemical reactions, offering potential benefits beyond zeolite research, and opening doors to career development opportunities.
