Experimental and computational studies on the adsorption of CO2 and N2 on pure silica zeolites

- Siliceous zeolites were synthesized in HF media with low defect concentration.
- Predictions of CO2 and N2 adsorption are in excellent agreement with experiments.
- Adsorption heats decrease with the increase of pore/window size for the adsorbates.
- GCMC is an effective model for CO2 and N2 adsorption on siliceous zeolites.
