Using inelastic neutron scattering spectroscopy to probe CO2 binding in grafted aminosilanes

Abstract

While a range of in situ characterisation techniques are available to probe CO₂ adsorption processes, inelastic neutron scattering is scarcely used, primarily due to the reliance on hydrogeneous modes. Materials capable of adsorbing CO₂, such as solid supported-amines contain a range of C–H and N–H species, which can be probed to explore the adsorption of CO₂. Here we show the benefits of using inelastic neutron spectroscopy to probe CO₂ adsorption with solid supported-amines, and the complementarity that can be achieved using different world-leading spectrometers.
