Reedijk Symposium 2019: Platinum electrodes: not as noble as you think
- Friday 25 October 2019
2333 CC Leiden
Platinum is used in many electrochemical cells, such as fuel cells and electrolysers, but also in many electroanalytical devices. Platinum has good catalytic activity for many reactions and is considered to be very noble and stable. In my talk I will discuss the basic surface electrochemistry of platinum and show how platinum electrodes roughen, disintegrate and deteriorate under oxidative and reductive conditions, and discuss the underlying mechanisms.
