Aerogels with their low density and high surface area are fascinating materials with great application potential especially in catalysis and photocatalysis. However, their advantageous morphology is still far from being fully exploited due to their limited compositional variety and low crystallinity. In addition, the high mechanical fragility prevents their use in the form of monoliths.Replacing the classical sol-gel approach by a particle-based assembly route represents a powerful alternative to expand the accessible functionalities of aerogels. Starting from nanoscale building blocks and ending with centimeter sized bodies, such a bottom-up approach expands over seven orders of length scales and the use of metal oxide nanoparticles combines the inherent properties with the highly porous microstructure.Although a careful thermal treatment increases the mechanical stability of aerogel monoliths, they typically remain rather fragile, and it is not possible to use them in liquid media without destroying their monolithic shape. Therefore, we will design a reactor that makes it possible to directly investigate aerogel monoliths in various gas phase reactions, especially in the photocatalytic reduction of CO2.The goals of the project are thus twofold: i) Development of a reactor to test the aerogels in the monolithic form as photocatalysts in diverse gas phase reactions, and ii) systematic variation of the composition of these nanoparticle-based aerogels to optimize their photocatalytic performance with the focus on CO2 reduction.
