Surfactant-free Colloidal Solutions for nano-Catalysts with enhanced properties

Projektbeschreibung

Neuer Weg zur Synthese metallischer Nanopartikel

Nanopartikel sind wichtige Nanomaterialien, die in vielen Bereichen Anwendung finden. Dank ihrer einzigartigen und exotischen Eigenschaften im Vergleich zu großen Mengen derselben Materialien, ihrer Fähigkeit zur bedarfsgerechter Funktionalisierung und ihrer extrem großen Oberflächen sind ihre Möglichkeiten geradezu grenzenlos. Bei der Nanopartikelsynthese kommen üblicherweise Tenside zum Einsatz, um die Aggregation von Nanopartikeln zu verhindern und ihre endgültige Form steuern zu können. In den meisten Fällen und besonders bei der Katalyse wirken sich diese Mittel jedoch nachteilig auf die folgenden Anwendungen aus. Das EU-finanzierte Projekt CoSolCat wird nun ein kürzlich patentiertes Syntheseverfahren erforschen und neue Produktionsstrategien entwickeln, die keine Tenside erfordern, um Nanopartikel herzustellen. Erwartungsgemäß werden die Erkenntnisse zu neuen und verbesserten Katalysatoren für die Industrie hinführen.

Ziel

CoSolCat is based on a new surfactant-free colloidal synthesis of precious metal nanoparticles developed and patented by the experienced researcher Dr J. Quinson. The technology has attracted interest from industries and a start-up has been created, yet is in its very early stages. Further research is required to fully seize and position the technology as a new state–of –the –art method to produce precious metal nanocatalysts.
The objectives of CoSolCat are to study in detail and develop further surfactant-free syntheses of precious metal-based nanoparticles to be used as catalysts with enhanced performances for the production of valuable chemicals and energy applications.
By combining world-leading expertise from the University of Copenhagen (Assistant-Professor Maria Escudero Escribano), Stanford (Assistant Professor Matteo Cargnello), a start-up and his own experience, Dr J. Quinson will produce, study, characterise, compare and so benchmark nanocatalysts obtained by the technology he patented, new routes to-be-developed in the project, and state-of-the art methods.
This will provide a deeper understanding of the production and properties of precious metal catalysts while the new technology will be more controlled and optimised to a degree relevant for industry. E.g. bi-metallic nanoparticles comprising a non-precious metal will be developed for the first time with new surfactant-free approaches and studied for model hydrogenation reactions. This research will lead to sustainable and affordable catalysts with improved selectivity.
The expertise gained by the applicant will (1) help to mature the technology, (2) develop a new pool of competences in heterogeneous catalysis in Europe, (3) provide expertise in industrially relevant production of catalysts suitable for a range of chemical productions and energy conversion reactions. The proposal is then directly relevant to provide world leading expertise in Europe for a green and more sustainable economy.
