Abstract

Heterogenous catalysis is probably the application of nanoscaled materials with the highest economic impact and instrumental in the solution of the energy and climate challenge. Oxides, especially complex oxides, are interesting functional materials for heterogenous catalysis. The property ‘catalytic activity’ is depending on certain particle characteristics (structural features such as primary particle size, fractal dimension, morphology, type and degree of agglomeration) which are directly measurable without additional processing steps. 

In this presentation we will show how chemical vapor synthesis (CVS) can be used to generate nanocrystalline oxide particles including complex oxides and how we can control and determine the particle characteristics relevant for heterogenous catalysis [1]. Photocatalytic water splitting using TiO₂ and Ga₂O₃ [2] and thermal oxidation of organic molecules by spinels and perovskites [3, 4] are used as examples.
