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.

The idea behind electrochemical CO<sub>2</sub> reduction is to convert CO<sub>2</sub> 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.
