N2 - Abstract The dynamic adsorption of toluene was investigated using supermicroporous silicas (SMPSs) synthesized through a solvent-free route by using tetraethoxysilane and conventional alkyltrimethylammonium halides as a structure-directing agent. The adsorption capacity of SMPSs depended on their pore diameters, which were precisely tuned in a range from 0.7 to 2.0 nm at single-angstrom intervals. The micropore filling of the molecule that is highly enhanced with micropores smaller than 1 nm improves the dynamic adsorption performance.
