An electrifying view on catalysis

The future of chemistry is ‘electrifying’: With increasing availability of cheap electrical energy from renewables, it will soon become possible to drive many chemical processes by electrical power. In this way, chemical products and fuels can be produced via sustainable routes, replacing current processes which are based on fossil fuels.

In most cases, such electrically driven reactions make use of so-called electrocatalysts, complex materials which are assembled from a large number of chemical componentAs. The electrocatalyst plays an essential role: It helps to run the chemical reaction while keeping the loss of energy minimal, thereby saving as much renewable energy as possible. In most cases, electrocatalysts are developed empirically and the chemical reactions at their interfaces are poorly understood. A better understanding of these processes is essential, however, for fast development of new electrocatalysts and for a directed improvement of their lifetime, one of the most important factors that currently limit their applicability.
