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.

Learning outcome

At the end of the course the students should:
- Understand the basis and driving forces necessary for the production of nanoparticles.
- Describe different mechanisms for nucleation ans growth of amorphous and crystalline nanoparticles.
- Understand the connection between thermodynamic drivig force and kinetics for the formation of nanoparticles.
- Understand the manufacture of porous alumina.
- Understand the fundamental principles for catalyst fabrication by precipitation, co-precipitation , "incipient wetness", sol-gel and use of colloidal particles.
- Present an overview of possibilites and likmitations in the application of catalytis modell systems.
- Derive the nucleation rate expressions for the formation of solid particles from solution.
- Calculate nucleation and growth rates for nanoparticles.
- Suggest ways of controlling particle size and particle size distribution based on changes in important system parameters.
- Calculate/suggest compostion of a solution for the fabrication of catalytic nanoparticles.
- Give examples for reaction – catalyst systems where the significance of particle size and/or the nano structure is identified.
- Data analysis and linear regression.

Further on evaluation

Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (60%) and a work (40%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade. If there is a re-sit examination, the examination form may be changed from written to oral. For a re-take of an examination, all assessments during the course must be re-taken.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
