The Department of Interface Science headed by Prof. Beatriz Roldan Cuenya at the Fritz-Haber-Institute is focused on the understanding of chemical reactions at gas/solid and liquid/solid interfaces of nanostructures for applications in the field of catalysis. The aim is to fully explore physico-chemical properties of highly controllable atomic surface structures.

1 Postdoctoral Position

We are currently looking for a postdoctoral researcher for the newly formed liquid phase electron microscopy group (https://isc.fhi-berlin.mpg.de/grp/seewee) at the Department of Interface Science.


Morphological Changes in Nanoscale Electrocatalysts during Electrochemical Cycling

The successful applicant will work with electrochemists in the Department to perform in situ transmission electron microscopy (TEM) experiments looking at nanoscale electrocatalysts under electrochemical cycling. These studies aim to investigate how electrocatalysts change under working conditions and understand how these changes affect their catalytic properties. Other responsibilities include routine characterization of samples from the Department using electron microscopy and its associated spectroscopic techniques. The Fritz Haber Institute has three TEMs on campus; a double-corrected JEOL ARM, an image- corrected Thermo Fisher Titan, and a Thermo Fisher Talos. The Department of Interface Science also has its own state-of-the-art environmental SEM.

PROJECT: In-situ nanoscale functional mapping of energy conversion materials

We offer a full-time postdoctoral researcher to work on the characterization of novel electro- and photoelectrocatalytic materials employing high spatiotemporal resolution atomic force microscopy under reaction conditions in liquid phase. Upon adapting existing cutting-edge AFM methodologies and protocols, the morphological and electronic properties of selected materials will be investigated in-situ / operando under external stimuli. Combined with advanced spectroscopic characterization tools and catalytic reactivity studies, nanoscale structure-property relationships at solid-liquid interfaces will be derived to guide the rational design of catalytic materials.

PROJECT: Thin film catalyst models

The topic of the project is the investigation of catalytic processes occurring on surfaces of thin film catalyst models. Such models mimic relevant aspects of a real world catalysts, but have a reduced complexity. In contrast, real world catalysts are very complex. This often prohibits to understand catalytic processes in detail, while this is more easily possible for catalyst models. Central aspects of the project are the development of thin film preparation recipes and the study of reactions at the surfaces. Several surface-sensitive experimental methods will be applied under vacuum conditions and at elevated pressures.

Unraveling the growth mechanism of shaped nanoparticles towards a rational design of novel catalysts for CO2 revalorization

There is an open PhD position in a joint proposal on nanoparticle (NP) research in the context of the Max-Planck-EPFL Center for Molecular Nanoscience and Technology.

The successful applicant will investigate the synthesis of novel nanoarchitectured catalysts as well as the evaluation of their reactivity. Both, the electroreduction of CO2 as well as its thermal hydrogenation, will be studied by means of H-type electrochemical cells and packed-bed mass flow reactors, respectively.

In collaboration with EPFL, we propose to derive mechanistic insights from the direct observation of NP nucleation and growth, to translate them into novel synthetic strategies, and to study the reactivity of such rationally designed catalysts. Exchange visits between both research centers are planned to give the student the opportunity to learn and use a broad range of techniques during his/her PhD and to collaborate with other students and scientists at the partner institution.

We are currently looking for a PhD student to support our Scanning Probe Microscopy group activities. The group has a long-standing expertise in this research field.

PROJECT: High Resolution Scanning Probe Microscopy of Model Catalysts

The topic of the project is the investigation of catalytic processes occurring on defined surfaces. The goal is to combine low temperature scanning tunneling microscopy (STM), atomic force microscopy (AFM) as well as its versatile spectroscopy modes together with standard Auger Electron Spectroscopy (AES) and Temperature Programmed Desorption (TPD) surface science methods on model systems, which are of relevance in the field of heterogeneous catalysis.
