Abstract
Nitrogen adsorption (NA) experiments yield diameter distribution densities V ( d ) of the random pore diameter d . Based on the assumed particle shape (circular cylinder, random diameter d ), the function V ( d ) can be transformed into a chord length distribution density (CLD) A ( l ). CLDs are connected with the porosity p of the material. The direct transformation step, V ( d ) → A ( l ), has been performed via Mathematica procedures. Small-angle scattering (SAS) experiments include information about the texture. Here, geometric information about pores and walls is intermixed into the correlation function γ ( r ). After separation of both effects, the determination of a pore size distribution from a CLD, γ ( r ) → V( d ), can be handled.
