abstract = {The combination of physisorption experiments with
simultaneous in situ small-angle X-ray and neutron
scattering (SAXS/SANS) was used to elucidate the porosity in
mesoporous silica with a trimodal pore structure. The
material ("KLE-IL") contains spherical mesopores of 14 nm in
diameter, worm-like mesopores (2-3 nm), and micropores,
templated by a block copolymer and an ionic liquid
surfactant, while the micropores originate from the
hydrophilic block of the block copolymer. The main objective
of the study was the quantification of the microporosity and
the small mesopores and to find out if they are indeed
located between the larger, spherical mesopores. Our in situ
SAXS/SANS experiments took advantage of contrast matching of
nitrogen (SANS, T = 77 K) and dibromomethane (SAXS, T = 290
K). By using the latter gas with a slightly larger kinetic
diameter, it was possible to judge the accessibility of the
pores under ambient conditions. The in situ experiments were
supported by high-precision ex situ physisorption. Using
suitable approaches for the SAXS/SANS analysis, it was
possible to separate the content of the micropores and small
mesopores.},
