Advanced transmission electron microscopy in catalysis

Awarded: NOK 2.0 mill.

Catalysis plays a crucial role in environmental and energy technology. The mechanisms of catalytic processes proceed at the atomic/molecular level and it is essential to understand these in order to improve existing systems and develop new ones. Metal and metal oxide particles, on a suitable support material, are the most important systems in heterogeneous catalysis. It is the composition, structure, size and surface properties of these particles and their interactions with the substrate that determine th e catalytic properties. Recent developments of modern instrumentation, particularly transmission electron microscopy (TEM), make it possible, in principle, to image and analyse particles of sizes down to 1 nm directly at the atomic level. This developme nt makes a rational design of catalytic materials a meaningful objective. Catalysis is an obvious fields for fast transfer of scientific development and basic knowledge into industrially and environmentally relevant applications. The relation between nano structure, composition and performance of several important catalytic systems will be addressed. The activity will be built around the new field emission gun TEM (FEGTEM) at the Department of Physics.
