a N2 adsorption–desorption isotherms for KIT-6 silica and the OMCs. The sorption isotherms for the OMC-0, OMC-1, OMC-4, OMC-8, and OMC-12 have been shifted vertically by 50, 550, 750, 1,200, and 1,450 cm3/g, respectively. b The corresponding pore size distributions for KIT-6 silica and the OMCs calculated from adsorption branches using the BJH algorithm
