The adsorption isotherms of N 2 gas at 77 K and CCl 4 vapor at 283.1 5 , 298.1 5 , and 308.1 5 K were measured for six samples of the mesoporous silicas having uniform cylindrical pores (MCM-41). The pore radii of the six samples (r p ), which were evaluated from the ฮฑ s plots of the N 2 isotherms,
