Course content

The course starts by deriving the thermodynamic driving force and the kinetics of nucleation and growth of nanoparticles by focusing on precipitation from solutions. Different mechanism for nucleation and crystal growth along with calculations of nucleation and growth rates define the basis for design of different particle populations and their application in different systems relevant for research and industry. Functionalisation of surfaces will be treated.

Methods for the fabrication of catalysts and catalyst supports based on precipitation are presented, as well as other methods with particular relevance for the catalyst nanostructure and functionality, like sol-gel and colloid based fabrication. Relevant examples where the significance of particle and pore size has been shown is presented (Au, Co, Ni- catalysts og carbon nano fibres (CNF)). A short introduction in catalytic modell systems and surface science and their experimental and theoretical application withibn cataluysis is also presented.
