Chemical Engineering / Chemical Catalysis
Prof. Dr. Franziska Heß 
The group does research in the area of computational modeling and simulation of heterogeneous catalyst systems. The special interest is in the modeling of catalyst stability and aging under realistic reaction conditions with the ultimate goal of identifying simple descriptors that enable the prediction of new catalyst materials that are both active and stable.
Chemical Engineering / Reaction Enineering of Heterogenic Systems
Prof. Dr. Reinhard Schomäcker 
The group works in the field of chemical reaction engineering, including reaction kinetics, design of new reactors and process concepts. Special attention is payed to the control of activity and selectivity of catalysts located in micro structured environments. For homogeneous catalysts surfactant based reaction media like microemulsions or micellar solutions are selected in order to optimize reaction conditions and catalyst recycling procedures simultaneously. For heterogeneously catalyzed reactions, where selectivity suffers from consecutive reactions, we study membranes as catalyst support materials , which allow very well defined contact between reactants and catalyst. The basis for all new concepts in reaction engineering are detailed kinetic investigation and the development of comprehensive kinetic models. In this field activities are focused on oxidation reactions of light hydrocarbons.

Prof. Dr. Peter Strasser
The „Electrocatalytic Energy Conversion Group“ is conducting basic research geared toward fundamental molecular understanding of surface catalytic reactivity on nanoparticle model catalysts. In particular we aim to probe, understand, and control the complex structural and compositional dynamics of multimetallic alloy nanoparticles at electrified interfaces and strive to elucidate how this dynamics affects the surface catalytic reactivity of the nanoparticle surface. The fundamental knowledge we generate impact and benefits the development of technological applications such as hydrogen fuel cells for automotive or portable applications, efficient photoelectrochemical hydrogen production by water splitting, next generation hydrogen storage technologies, or carbon capture strategies. The group is collaborating with industrial partners as well as international academic partners, in particular the University of Houston, Stanford University, Massachusetts Institute of Technology (MIT), and Argonne National Laboratory. One catalytic process of great importance in our group is the splitting of water into oxygen and hydrogen as well as its reverse process of water production in a fuel cell. The oxygen reduction reaction with its prohibitively high overpotential is a major scientific priority. To achieve our goals we use (i) solid-state thermal and surfactant-assisted particle synthesis methods, (i) modern synchrotron radiation methods such as, anomalous X-ray diffraction (AXRD), anomalous Small Angle X-ray Scattering (ASAXS), X-ray Photoemission and other spectrodcopy as well as Electron microscopy (SEM, STEM) for characterization of particles size and composition dynamics ex-situ and in-situ. Finally for functional characterization we apply electrochemical characterization methods such as the Rotating Ring Disk, Gas diffusion layer testing as well as Single Fuel Cell Testing up to 300 W output power. The „HetCat“ group is the center of a parallel research thrust, embedded in the newly establish center of excellence in Catalysis („Unifying concepts in catalysis“) consist of the development and characterization of novel catalyst materials for methan, CH4, upgrading by, for instance, oxidative coupling to C2 products. While poorly understood, a tremendous commercial potential lies behind this catalytic process.
Prof. Dr. Roel van de Krol 
Roel van de Krol is head of the Insitute for Solar Fuels at the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), and professor at the Chemistry Department of TU Berlin. After earning his PhD from TU Delft in 2000 and a postdoctoral stay at M.I.T. (USA), he returned to TU Delft where he was an assistant professor until 2012. At HZB, his research focuses on the development of materials and devices for the photoelectrochemical conversion of sunlight to chemical fuels. Understanding how surface and bulk defects in thin films and nanomaterials affect light absorption, charge transport, recombination and catalytic activity is at the heart of these efforts. At TU Berlin, he teaches a course on Photo-Electrochemical Energy Conversion in the winter semester.
