Description

Uio-66-So3H CAS NO 1334722-07-4 is a sulfonated metal-organic framework (MOF) derived from the renowned UiO-66 structure, functionalized with strong sulfonic acid (-SO3H) groups. This modification imparts exceptional Brønsted acidity and high proton conductivity, making it a superior solid acid catalyst and proton exchange material. It is critically needed by researchers and manufacturers in the chemical, energy, and environmental sectors for advanced catalytic processes and next-generation fuel cell development.

Application

• Solid Acid Catalysis: Used as a highly efficient, reusable heterogeneous catalyst for acid-catalyzed organic reactions such as esterification, acetalization, and biomass conversion.
• Proton Exchange Membranes (PEMs): Serves as a functional filler to enhance proton conductivity and stability in membranes for fuel cells and other electrochemical devices.
• Gas Separation & Storage: Leverages its porous structure and functional groups for selective adsorption and separation of gases like CO2, H2, and CH4.
• Water Purification: Applied as an adsorbent for the removal of heavy metal ions and organic pollutants from wastewater due to its high surface area and sulfonic acid sites.
• Sensor Development: Utilized in the fabrication of chemical sensors where its porous structure and functional groups enable selective detection of analytes.
• Drug Delivery Systems: Investigated as a nanocarrier for controlled drug release, benefiting from its tunable porosity and surface functionality.

Quality Control

Our Uio-66-So3H is produced and tested under stringent quality management protocols. Each batch undergoes comprehensive analysis including phase purity (PXRD), surface area (BET), and functional group quantification (EA, titration) to ensure consistent performance as a catalyst and functional material. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation of the material's catalytic activity and structural integrity.
