  •  EDELKAT - A toolbox for optimized electrocatalysts           Bildergebnis für BMBF              
     

BMBF NanoMatFutur project (Jan. 2014 - Dez. 2019)

In this project we develop novel nanostructured electrocatalysts, in which the catalytically active components (e.g. platinum or noble metal nanoparticles) are stabilized against electrochemical sintering.

In this context, we particularly focus our efforts on yolk@shell structures.

We thereby developp novel atom efficient and one-pot synthetic routes towards yolk@shell nanostructures and investigate their applicability in electrocatalysis and in particular in fuel cell relevant  reactions.
