Tailored nanosized metal catalysts for improving activity and selectivity via engineering of their structure and local environment

Objective

Production of better than existing pharmaceuticals, healthy food ingredients, perfumes, other fine chemicals, which are of immense importance for improving quality of life, is often limited by low selectivity in their synthesis over heterogeneous catalyst s. Selectivity of these catalysts, bearing metals of nanoparticle size, could be enhanced by carefully adjusting the size and environment of metal nanoparticles. The project is aimed to study the influence of metal nanoparticle size and its environment o n catalytic behaviour in some representative reactions of industrial importance and, finally, to establish the fundamental knowledge on atomic/molecular level relating the nanocatalyst synthesis and behaviour. The model reactions represent selective oxid ation, chemo- and enantioselective hydrogenations as well as catalytic isomerisation reactions, where the use of conventional supported catalysts yields to too low selectivities of the desired products. By changing the size, shape and local environment o f the nanostructures, their functionality may be controlled. To achieve the main goal, following tasks will be performed: i) development and physico-chemical characterisation of Ru, Pt, Pt-Au and Pd nanoparticles of 1-10 nm diameter incorporated in inor ganic and organic functionalised and non-functionalised micro-mesoporous matrices, polymer or carbon nanofibers, ii) catalyst testing in hydrogenation and oxidation , yielding the intermediates used for production of biologically active compounds, health y food incredients and parfumes, iii) development of reaction mechanisms by combination of diffusion and kinetic modeling together with time dependent Monte Carlo - quantum chemical calculations. The obtained results will allow finding correlations betwe en the nanoparticle size-shape-environment and catalytic behavior. Prevention of metal leaching by incorporating metal nanoparticles in matrices allowing catalyst reuse will be studied.
