Multifunctional catalysts

Multifunctional catalysts

Supraparticles can provide an emergent, tunable porosity and precisely configurable accessibility of active catalyst sites, thus, enhanced catalytic activity and stability. Their flexible setup also permits the integration of multiple different building blocks, which allows for coupling interactions within the material, e.g., energy transfers, or the addition of further functionalities such as an inductive heatability of the systems. For the direct application of supraparticles in catalytic fixed-bed reactors, their attachment on beads, yielding ‘suprabeads’, is a strategy to increase their size regime without compromising their unique supraparticle-based functionality.
