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!

01/2020 Qing and Martin summarize recent ideas in electrocatalytic nitrogen reduction

Qing and Martin published the minireview "Overcoming Chemical Inertness under Ambient Conditions ‐ A Critical View on Recent Developments in Ammonia Synthesis via Electrochemical N2 Reduction by Asking Five Questions" in ChemElectroChem. We are working together on this intensely reserached topic now for more than two years and give a rather personal view on the question where we do see the major room for improvement for electrocatalytic ammonia synthesis in the near future.

01/2020 Milena`s review paper published in Advanced Functional Materials

Milena`s paper entitled "From Molecular Precursors to Nanoparticles-Tailoring the Adsorption Properties of Porous Carbon Materials by Controlled Chemical Functionalization" has been published in Advanced Functional Materials. Together with Qing and Martin, she gives an overview on a couple of different synthetic methods to change the electron density distribution in porous carbon materials to control their properties in adsorption and catalysis. The article reflects the idea of the research our group is following. Congratulations Milena for a great 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.
