The formal potentials and electrode kinetics of the proton/hydrogen couple in various room temperature ionic liquids.

چکیده
The Hydrogen evolution reaction has been quantitatively investigated at a Pt electrode in series of room temperature ionic liquids vs. Ag/Ag(+) redox couple. The measured formal potentials of the H(2)/H(+) (HNTf(2)) redox couple in each RTIL reveals a dependence on the nature of anion, suggesting significant interaction between proton and anion.
