HEALECTRO: design principles for self-healing electrocatalysts

The dissolution of electrocatalysts during operation is one of the key limiting factors in electrochemical technologies such as green hydrogen production and the conversion of CO2 to chemicals. Self-healing electrocatalysts have the potential to mitigate this degradation process: by balancing electrocatalyst dissolution with redeposition reactions, an equilibrium is created which, in principle, endows the electrocatalyst with an infinite lifespan. In HEALECTRO, I will combine high-throughput experimentation and advanced X-ray spectroscopies to unravel how the structure of self-healing catalysts can be steered to combine this long lifespan with efficient catalysis.
