Abstract

Abstract A theoretical model for pore size estimation of mesoporous materials was presented in this paper. It is based on the statistical thermodynamic model of micelle formation proposed by R. Nagarajan. The proposed model was applied to predict the pore size of MSU-X molecular sieve prepared in different synthetic systems. The estimation results were compared with reliable experimental measurements. The level of deviation is acceptable with the substantial simplifications included in the model. Hansen solubility parameter and Dimroth-Reichardt parameter were introduced to explain the discrepancies. The proposed model may help to screen suitable synthesis conditions and guide the controllable synthesis of molecular sieve to some extent.
