Zusammenfassung der Projektergebnisse

Aerogels are unique solid materials with extremely low densities, high porosity, and large inner surface area. They combine the chemical and physical properties of nanomaterials with those of the macroscale and may integrate the specific properties of the various constituents in one resulting material, making aerogels very attractive in various applications such as (electro-) catalysis, thermoelectrics, and sensors. In this project we have developed new approaches to the formation of mixed aerogels based on various combinations of semiconductor and noble metal nanoparticles. The aerogels were characterized by a variety of microscopic, spectroscopic and analytical methods. Processes of energy and electronic transfer are investigated and described. For various aerogel systems, formation mechanisms are elucidated. Application potential as optical sensors, colour conversion materials and electrocatalysts is demonstrated.
