Description

ZIF-70 is a highly porous, crystalline metal-organic framework (MOF) material belonging to the zeolitic imidazolate framework family. Its unique structure, characterized by a high degree of flexibility and tunable pore size, makes it an exceptional candidate for advanced gas separation and storage applications. This material is particularly valuable for researchers and engineers in the fields of carbon capture, hydrogen storage, and heterogeneous catalysis, where selective adsorption properties are critical.

Application

• Gas Separation & Purification: Selective adsorption of CO₂ from flue gas or natural gas streams, and separation of other industrially relevant gas mixtures.
• Energy Storage: Investigation as a porous scaffold for the physisorption-based storage of hydrogen and methane.
• Catalysis: Serving as a heterogeneous catalyst or catalyst support due to its high surface area and well-defined active sites.
• Sensing Technologies: Development of chemical sensors that exploit framework structural changes upon guest molecule adsorption.
• Drug Delivery Systems: Exploration as a biocompatible nanocarrier for the controlled release of therapeutic agents.
• Advanced Materials Research: Fundamental studies on MOF flexibility, gate-opening phenomena, and adsorption mechanics.

Quality Control

Our ZIF-70 is synthesized and handled under controlled conditions to ensure batch-to-batch consistency and high performance. Each lot undergoes rigorous characterization, including analysis of phase purity, surface area, and pore volume. A Certificate of Analysis (COA) detailing specific test results is provided with every shipment to guarantee compliance with your research and development specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material should be stored in a cool, dry place, ideally under an inert atmosphere such as argon or nitrogen to maintain its structural integrity and adsorption capacity. Long-term storage is recommended at room temperature (15-25°C) in a desiccator.
