Description du projet
Étude du monde atomique des nanoparticules enrobées de graphène
Concevoir, caractériser et comprendre les propriétés d’une nouvelle famille de particules au niveau atomique est une tâche complexe et exigeante qui requiert des connaissances et une expertise pluridisciplinaires poussées. Le projet GRANN, financé par le Conseil européen de la recherche, est une initiative de recherche interdisciplinaire qui a pour objectif de synthétiser une nouvelle famille de nanoparticules enrobées de graphène monocouche et de nanograins de graphène de haute qualité. Il étudiera leur activité catalytique, leur stabilité chimique ainsi que leurs caractéristiques optiques en vue d’une utilisation potentielle dans les domaines de la catalyse industrielle, des cellules solaires et de la chimie interstellaire. Le projet réunira des experts en science des surfaces, en optique, en nanoscience et en astrophysique afin de développer de nouveaux systèmes susceptibles de servir de premiers modèles de laboratoire de nanoparticules catalytiques pour la chimie des surfaces interstellaires.
Objectif
In a truly cross-disciplinary research project encompassing surface science, optics, nano-science, astrophysics and chemistry we will synthesize a novel family of high quality mono-layer graphene coated nanoparticles and graphene nanograins with new chemical and optical properties and investigate their catalytic activity, chemical stability and optical characteristics to gauge their relevance for and applicability in industrial catalysis, solar cells, and interstellar chemistry.
This will be accomplished by extending existing expertise, knowledge and methods developed by us and by international colleagues for graphene synthesis, graphene reactivity and chemical functionalization, graphene coatings on industrially relevant samples and interstellar surface astrochemistry on carbonaceous materials, into the nanoparticle regime. Combined with state-of-the-art surface science characterization methods with emphasis on scanning tunnelling microscopy and spectroscopy, high resolution transmission electron microscopy, X-ray photoelectron spectroscopy, and thermal desorption mass spectrometry, complemented by Raman and transmission spectroscopy, this will enable us to design, characterize, and understand the properties of this new family of particles at the atomic level.
The vision is to harness and combine the remarkable properties of graphene and nanoparticles to create systems with entirely new and unexplored characteristics, to tune these characteristics to be useful for real-world applications, and to exploit the new systems as the first realistic laboratory models of catalytic nanoparticles for interstellar surface chemistry.
This ambitious and cross-disciplinary research program will predominantly take place at the Surface Dynamics Laboratory at Aarhus University which is headed by the applicant, but will also involve local, national and international collaborators.
