In this work, highly ordered mesoporous silica, SBA-15, with different pore structure were prepared as model materials for the evaluation of thermoporometry. The mesoporous structure (pore size distribution, specific surface area, pore volume, etc.) was determined both by Thermoporometry and Ar gas adsorption/desorption measurements independently and the estimation of thickness of the non-freezable water(tnf) are carried out. The comparision of tnf value between our results and other papers will be discussed.
