Накратко на български
Метални комплекси и клъстери върху повърхности се анализират на атомно ниво, за да се разбере как структурата им влияе върху химичните реакции. Това помага за създаването на по-ефективни катализатори за производството на горива, пластмаси и лекарства.

Study of uniform supported metal complexes and metal clusters at atomic level for catalytic applications
Catalysts accelerate chemical reactions and are keys in the production of fuels, plastics, pharmaceuticals, and others. Most catalysts are solids incorporating metals as the active sites. To achieve optimum performance, it is necessary to understand how the structure of the sites affects their catalytic properties. The complexity of common industrial catalysts hinders this understanding, because they consist of mixtures of structures whose role cannot be resolved unambiguously. In contrast, when the active sites are synthesized to be simple and uniform, a solid basis for designing new materials is established. We anchored metals in well-defined structures onto surfaces with variable characteristics. The structure of the metal sites was tuned at a molecular level by treatments in controlled atmospheres, with the changes being precisely determined via state-of-the-art spectroscopy and microscopy. Correlations between the structures and the catalytic performance enabled the design of improved catalysts, some with excellent potential to replace current technological catalysts.

Цел на проекта
The discovery and optimization of materials with nanometric dimensions (e.g. supported metal clusters) has aroused high interest in catalysis field during the last years. Based on the fact that some elements, such as gold, show unique catalytic properties when properly synthesized in the form of small crystallites, attention has been mainly paid on controlling the physical-chemical characteristics of the supported nanoparticles at atomic scale, taking into account that this matter is crucial for designing more active and selective catalysts. Particularly, the possibilities of supported metal species containing only a small number of atoms (1–10 metal atoms) are of high interest for application in catalysis, since they no longer act like bulk metals, but tend to offer unique properties in the activation of chemical functionalities. During the present project, we will tackle the synthesis, characterization and reactivity of supported metal complexes, and small metal clusters, for producing solid metal-based materials with properties close the molecular analogues. A hypothesis underlying the research is that these well-defined supported species play a key role in advancing the fundamental understanding of catalysis, in such a way that the study of much more complex nanoparticulated materials (industrial catalysts) can be built on the foundation of this research.
