Research Interest

About 80% of all catalyzed chemical reactions used worldwide are being heterogeneously catalyzed with the probably most prominent example being the exhausted catalyst in cars, electrocatalysts in fuel cells and electrolyzers and the broad zoo of catalysts used in chemical industry to synthesize basic chemicals. A large fraction of the materials used hereby are so-called supported catalysts which consist of a support material with large surface area and one or several (often) nanoparticulate co-catalysts. The catalytic activity and selectivity of such materials as well as the rational design to maximize the product yield is generally related to the interaction between co-catalyst and the support leading to the formation of a high number of so-called “active sites”. Yet, in heterogeneously catalysed reactions the mechanistic correlations between catalytic activity and dynamically changing catalyst structure (size of support and co-catalyst, crystallinity, existence of defects) as well as general materials properties (composition, band structure, charge carrier density etc.) required to determine or even predict the density of active sites participating and forming during the reaction remains a huge challenge. Expanding our general knowledge and understanding of the formation and type of active sites in different catalytic reactions strongly supports to purposefully design nanomaterials and catalysts strongly required for an economic and indulgent development of new sustainable technologies. When considering current discussions on mining rare-earth elements or lithium required in many of our modern technologies this aspect appears to be even more important.

With the technological vision mentioned above in mind the junior research group of Dr. Sven Reichenberger aims to contribute by using the extraordinary properties of laser-generated nanoparticle (co-catalyst) and laser-based colloidal post-processing (support) to synthesize and provide gradually tuned and tailored heterogeneous catalysts with individually adjusted composition (of co-catalyst and support), above mentioned materials properties, size and loading (of co-catalyst). To achieve this purpose, pulsed laser ablation in liquids (LAL) is used and studied to fabricate surfactant-free nanoparticles with high purity (no surfactants used!) and controlled size distribution of a wide variety of materials including metals, oxides, and alloys. The laser-based synthesis is linearly scalable and generally allows to fabricate heterogeneous catalysts by colloidal deposition of the nanoparticulate co-catalyst on support materials (also metals, oxides, sulfides, nitrides, carbides, graphenes, etc.) in desired and (mostly) freely choosable mass/surface loading. To alter the properties of the support material (or the final supported catalyst) a colloidal pulsed laser post-processing (cLPP) method is used and further developed with the aim to understand the occurring laser-induced materials property changes allowing to gradually create (or remove) material defects, tune optical properties (e.g. bandgap, photoluminescence), composition or exposed crystal phases for heterogeneous catalysis studies. While our internal research projects aim at improving our method by improving our insight on the laser-materials interaction and mechanisms of laser-based materials property changes, we continuously seek for national and international collaborations with experts in materials and surface analytics and heterogeneous catalysis research and development.
