High purity Sulfhydryl Functionalised Silica is a specially chemically treated silica material characterized by its surface modification with sulfhydryl (SH-) functional groups. This modification endows the silica with new chemical properties and broad application potential. High purity Sulfhydryl Functionalised Silica typically exhibits excellent adsorption performance, chemical stability, and thermal stability, maintaining its properties in various complex environments.

II. Applications

1. Metal Adsorption and Removal:
2. Due to the strong affinity of its sulfhydryl functional groups for metal ions, High purity Sulfhydryl Functionalised Silica is widely used to adsorb and remove metal ions from solutions, particularly precious metals such as palladium (Pd) and platinum (Pt). In drug synthesis and fine chemical production, this silica can effectively remove residual metal catalysts after reactions, improving product purity and safety.
3. For instance, in drug synthesis, Pd-catalyzed coupling reactions often leave behind trace amounts of Pd residues, which may be toxic to humans. Using High purity Sulfhydryl Functionalised Silica can efficiently remove these residual Pds, ensuring the safety and efficacy of drugs.
4. Environmental Purification:
5. In wastewater treatment and air purification, High purity Sulfhydryl Functionalised Silica can also be used to adsorb and remove harmful heavy metal ions and organic pollutants, contributing to improved environmental quality.
6. Catalyst Support:
7. Thanks to its excellent chemical and thermal stability, High purity Sulfhydryl Functionalised Silica can serve as a catalyst support for various chemical reactions. By loading specific catalyst active components on its surface, efficient and stable catalyst systems can be prepared.
8. Other Applications:
9. In microelectronics and biotechnology, High purity Sulfhydryl Functionalised Silica also has potential applications. For example, in microelectronics manufacturing, it can be used to prepare high-purity chemical reagents and gas purification materials; in biotechnology, it can be used to immobilize enzymes, cells, and other biomolecules, enabling continuous and efficient biocatalytic reactions.
