Proton-donating and chemistry-dependent buffering capability of amino acids for the hydrogen evolution reaction
John Brown, Alexis Grimaud
Abstract
Amino acids can act as proton donors and have sufficient buffering action to sustain H 3 O + reduction at large current density. However, the buffering capacity is dependent on the proximity of the isoelectric point (pI) and buffering p K a .
