Step Potential Electrochemical Spectroscopy of Proton Intercalation in γ /  ∈  ‐ MnO2

Abstract

Among the numerous varieties of MnO 2 , the γ/e forms are the most active towards proton intercalation. We have applied a specific electrochemical spectroscopy technique to these compounds in an attempt to identify the successive steps of proton intercalation and the origin of its partial-only reversibility
