Pt has been remarkable Hydrogen Evolution Reaction electrocatalyst in Acid which perform good even in large scale electrolysers.
While there are plenty of engineered HER catalyst reports most of them fail at reasonably high currents and long term testing. I wonder if there is any catalyst with higher intrinsic activity than Pt?
Thanks

Dear Aaditya
Then main important feature of Pt, by which makes it an ideal option, is the fact that Pt is a noble metal. For electrodeposition studies in acidic media, you have no concern about the possible dissolution of Pt. Therefore, you can focus on the mechanism of hydrogen evolution. I think you can also use other noble metals such as Pd, Ag, etc..
