Bridging the Gap between Structurally Distinct 2D Lamellar Zeolitic Precursors through a 3D Germanosilicate...

Area of Science:

• Materials Science
• Inorganic Chemistry
• Nanotechnology

Background:

• Lamellar zeolitic materials are of significant interest for diverse technological applications.
• Traditional synthesis of 2D zeolitic precursors is established, but inter-conversion between distinct 2D structures remains a challenge.
• This synthetic obstacle limits the variety of zeolites constructible from layered precursors.

Purpose of the Study:

• To report a novel Ge-recycling strategy for topotactic conversion between different 2D zeolitic precursors.
• To overcome the synthetic limitations in constructing diverse zeolite structures from layered materials.

Main Methods:

• A Ge-recycling strategy was employed for topotactic conversion.
• A three-dimensional (3D) germanosilicate intermediate was synthesized.
• The intermediate was constructed rapidly (within 150 minutes) by leveraging structural similarity with the parent lamellar precursor.

Main Results:

• Successful topotactic conversion between distinct 2D zeolitic precursors was achieved via a 3D germanosilicate intermediate.
• The synthesis of the intermediate germanosilicate was efficient, completed within 150 minutes.
• The strategy effectively overcomes the synthetic barrier between different families of zeolitic materials.

Conclusions:

• The developed Ge-recycling strategy enables facile inter-conversion of 2D zeolitic structures.
• This approach expands the possibilities for synthesizing novel zeolite architectures.
• The method addresses a key synthetic challenge in lamellar zeolite chemistry.
