03/2020Welcome to the new PostDoc Amrita Chatterjee

Dr. Amtrita Chatterjee joined the group as new PostDoc! Amrita will work an anode materials for lithium- and sodium-based batteries. Welcome to the group, Amrita! We wish you all success with your projects!

03/2020 Papers published by Kai Xiao and Karen Leus

Our collaborations with Dr. Karen Leus from Ghent University and Dr. Kai Xiao from the MPIKG have resulted in two publications. Karen`s paper entitled "Covalent Triazine Framework/Carbon Nanotube Hybrids enabling selective reduction of CO2 to CO at low overpotential" has been published in Green Chemistry. We describe how covalent triazine frameworks can be grown on carbon nanotubes and how the resulting materials perform as electrocatalysts in carbon dioxide reduction. Kai`s article "Ultrathin 2D graphitic carbon nitride @ metal films: underpotential sodium deposition in adlayers for sodium‐ion batteries" describes the activation of sodium deposition by carbon nitride thin films. The work appeared in Angewandte Chemie. Congratulations to K and K!

01/2020 Prof. Roland Marschall is our guest

Prof. Roland Marschall from the Universität Bayreuth visited the MPIKG and the University of Potsdam. He gave the lecture entitled "Nanostructured Fe-based materials for photcatalysis and photoelectrochemical water splitting". Thank you very much for following our invitation and for a day full of inspiring discussions, Roland!

01/2020 Visit of Prof. Philipp Adelhelm

Prof. Philipp Adelhelm from the Humboldt-Universität zu Berlin (chair of Physical Materials Chemistry - Electrochemistry) visited us in Golm. Philipp gave the GDCh invited lecture "Material aspects of alternative energy stores: Sodium-ion and solid-state batteries". Many thanks for your visit and the inspiring discussions, Philipp!

01/2020 Runyu`s paper published in CARBON

Together with collaborator Prof. Feixiang Wu from Central South University in Changsha, Martin and Runyu published the paper entitled "Towards stable lithium-sulfur battery cathodes by combining physical and chemical confinement of polysulfides in core-shell structured nitrogen-doped carbons" in CARBON. We report the synthetic design of core-shell structured nanoporous carbon materials, which leads to combined physical and chemical polysulfide confinement and enhances the stability of lithium-sulfur battery cathodes. Congrats to Runyu and Feixiang for the nice piece of work!

Energy and Environmental Utilization of Carbon Nanomaterials

The main area of research in our group is the development of nanostructured carbon materials with tailored properties for energy and environmental applications. Especially nanoporous materials with high internal porosity are of interest because they combine large available surface area of several 1000 m2/g with high chemical/thermal stability and electrical conductivity. Suchlike structures are key components in future energy storage applications, gas purification, and as support materials for metal nanoparticles in heterogeneous catalysis and can thus contribute to a sustainable development of our societies` energy balance.

We use advanced templating approaches on the nanoscale to tailor the pore size, pore geometry, and pore connectivity of these materials with high precision. Furthermore, heteroatom doping is used to modify the electronic properties and surface chemistry of the carbon framework. The performance of the designed carbon materials in gas adsorption, electrochemical energy storage (batteries and supercapacitors), and heterogeneous catalysis are linked to their textural and electronic properties. In this way, a better understanding of the structure-performance relationships can be achieved for the respective applications.
