Abstract

BPH-type synthetic aluminosilicate zeolite (Linde Q) nanosheets are synthesized at room temperature without organic structure-directing agents (OSDAs). The BPH nanosheets (7 nm thick, 90 nm across; Si/Al = 1.3) are formed in a colloidal suspension using a mixture of structure-directing cations (Cs+, K+, and Na+). In situ XRD reveals the high stability of the BPH nanosheets up to 500 °C under vacuum (0.021 mbar) due to the presence of Cs+. The high CO2 adsorption capacity (3.78 mmol/g) and stability of the BPH nanosheets open the door for the preparation of oriented thin films and membranes for gas separation applications.
