Austrian Academy of Sciences (ÖAW) Technische Universität Berlin Fritz Haber Institute Max Planck Society Lawrence Berkeley National Laboratory University of California at Berkeley Professor Günther Rupprechter (born July 1, 1966, in Jenbach, Austria) is an Austrian scientist, full professor and currently Head of the Institute of Materials Chemistry,[1] Technische Universität Wien (TU Wien).

Part of the thesis work was carried out at the Max Planck Institute of Microstructure Physics (Halle an der Saale, Germany).

Lawrence Berkeley National Laboratory (1996–1998 with Prof. Gábor A. Somorjai),[8] Rupprechter became Group Leader for Laser Spectroscopy & Catalysis (1998–2006) at the Fritz Haber Institute, Max Planck Society, Chemical Physics Department, Berlin, Germany.

His research group[9] employs a four-pronged approach: Rupprechter's overarching goal is to elucidate the molecular mechanisms of reactions relevant to a clean environment, energy conversion, and efficient resource utilization.

Materials of interest include mono- (Pt, Pd, Rh, Cu, Ni, Au, Co) and bimetallic (PdZn, Pd2Ga, PdCu, CuNi, CuZn, PdAu, AgAu, CuAu, RhAu) nanoparticles on supporting (mixed) oxides (Al2O3, SiO2, CeO2, PrO2, ZrO2, TiO2, ZnO, MgO, Ga2O3, Co3O4), perovskites (LCO, LSF), and carbon (HOPG, GR, GR-NPs).

Since Oct. 1st, 2023, Prof. Rupprechter holds the position of "Director of Research" of the FWF-funded Cluster of Excellence "Materials for Energy Conversion and Storage (MECS).

[20] Rupprechter has (co-)organized of academic conferences and summer schools, e.g. the annual "International Workshop on Chemistry and Physics of Novel Materials"[21] (with P. Blaha), the EFCATS Summer School "Engineering Materials for Catalysis 2020" (with Albin Pintar and Nataša Novak Tušar: Portorož-Portorose, Slovenia), the Faraday Discussion on “Photoelectron Spectroscopy: New Horizons in Surface Analysis", London, UK (2022), the "GÖCh-Symposium - Physikalische Chemie und Elektrochemie in Österreich 2023"[22] and the upcoming 16th Pannonian International Symposium on Catalysis (Seggau/Styria, Austria; September 1–5, 2024; with C.

[53][54] Field electron microscopy (FEM) is applied to image an ongoing catalytic reaction on the facets of an individual metal nanocrystal in real time, enabling, e.g., to resolve interfacet coupling and its collapse due to surface restructuring.

[55][56][57] When the produced water was used as imaging species, the active sites were directly identified by in situ field ion microscopy (FIM).
