Vibrational study of the various forms of (solvated or unsolvated) mobile proton in materials for storage and production systems based on the hydrogen vector. Advantages, limitations and open questions

Abstract

The desire to use hydrogen as an energy carrier requires a better knowledge of the materials that can serve as electrolyte or electrode, i.e. solids containing mobile protons. We present here through some examples the contribution and the limits of vibrational spectroscopies (Infrared, Raman and inelastic neutron scattering) to understand the structure and dynamics of proton species and discuss the questions to be resolved.
