摘要：
The experimental thermodynamic characteristics of CO probe molecule adsorption on lithium exchanged zeolites of MFI, FAU, MCM-58, MCM-22, MCM-36 and MCM-49 structure was investigated by joint volumetry-calorimetry method. Consideration was given to the interpretation of the heat evolved when a probe molecule was adsorbed on the surface. In particular, the number and strength of adsorption sites were discussed as functions of zeolite structure and concentration of extra-framework cation. In addition, the obtained thermodynamic data and energy distribution functions were discussed together with results obtained from FTIR spectroscopy and theoretical DFT calculations.
