Research Projects

Many industrial applications are highly dependent on precious metals such as platinum. Eminently, the use of precious metals in new, evolving technologies is being impeded on a large scale due to their low abundance and high costs. Here, a higher availability of cost-efficient catalyst materials is utterly desirable. Therefore, our aim is to reduce the amount of noble metals while keeping the activity and especially the stability up. Read more
Water electrolysis as a key technology for the storing of renewable electricity is one of the principal research areas in our group. Targeted efficiency of water electrolysis is still serious challenge predominantly due to the limitations in the performance of anode reaction – oxygen evolution reaction. Read more
Oxygen reduction reaction is studied by combining different approaches in a concerted way. Read more
The idea behind electrochemical CO2 reduction is to convert CO2 into chemical compounds like methane, methanol or carbon monoxide (for Syngas), that can serve as energy storage and can be used to compensate energy fluctuations from renewable energy sources by classical combustion or in combination with fuel cells. Therefore this approach is also referred as the artificial carbon dioxide cycle. Read more
