Small‐Angle Neutron Scattering for In Situ Probing of Ion Adsorption Inside Micropores

Abstract

Confined ions: The high penetrating power and sensitivity of neutron scattering to isotope substitution are harnessed to observe changes in the ion concentration in a porous carbon material as a function of the applied potential and the pore size. Depending on the solvent properties and the solvent-pore-wall interactions, either enhanced or reduced ion electroadsorption may take place.
