Offer for a 18 month-post-doc position.

 

For what purpose? Preparation of supported metal catalysts: Decomposition by cold plasma of organic agents stabilizing metal colloids after adsorption on an oxide support

Where? in Paris, University Pierre et Marie Curie (now Sorbonne Université)

With whom? Dr Catherine Louis (Lab. Réactivité de Surface) and Dr Jérôme Pulpytel (Lab. Interfaces et Systèmes Electrochimiques)

When? Possible to start as soon as possible

How much? Net monthly salary: around 2100 euros

The project deals with the preparation of supported metal catalysts obtained from the deposition of metal colloids onto oxide supports. An advantage over preparations based on deposition of metal precursors followed by thermal treatments, is that the size of the metal nanoparticles is expected to be better controlled.

However, it is also well established that the organics stabilizing the colloids are detrimental for gas phase reactions, and must therefore be eliminated after deposition. Most often, this is performed through thermal treatments, which are efficient, but detrimental for the metal particle size. To avoid metal particle sintering and broadening of size distribution, the use of cold plasma will be investigated, in collaboration with a specialist of plasma, Dr Jérôme Pulpytel

Hence, the project involves: synthesis of colloids, catalyst preparation, plasma treatments, characterization by XPS and electron microscopy and possibly other techniques, and catalytic reactions in gas phase.

The candidate must have a PhD, if possible with a background in colloid chemistry and/or heterogeneous catalysis.

 

The application will include a motivation letter, a curriculum vitae, a list of publications and the names and contacts of at least one referee.
