The “volcano”-relationship for the electrocatalytic hydrogen evolution reaction seems to be a generally accepted phenomenology in electrochemistry. Based on the Sabatier principle, which suggests a not too strong, nor too weak binding of reaction

The performance of proton-exchange membrane fuel cells (PEMFCs) is defined by the equally important parameters of the intrinsic activity and stability of the electrocatalysts. This work focuses on the stability of carbon supported high surface area o

Metallic iridium and ruthenium as well as their oxides are among the most active oxygen evolution (OER) electrocatalysts in acidic media, and are also of interest for the catalysis of the hydrogen evolution (HER). The stability of these materials und
