{"product_id":"zif-820-um","title":"ZIF-8(20 um)","description":"\u003cp\u003eProduct Name ZIF-8(20 um) Product Overview ZIF-8 (Zeolitic Imidazolate Framework-8) is a metal-organic framework material with high crystallinity and porosity, composed of metal ions (such as zinc ions) and organic ligands (such as 2-methylimidazole). Co-precipitation is a commonly used method for preparing ZIF-8. The basic principle is to mix metal salts and organic ligands in an appropriate solvent, and control the reaction conditions to make them react and generate ZIF-8. However, ZIF-8 prepared by simple co-precipitation is difficult to grow beyond micrometer-sized dimensions under natural growth conditions. By introducing a specific amount of monodentate ligands (such as sodium formate) during synthesis, competitive coordination can be achieved to suppress the coordination rate, thereby generating larger ZIF-8 crystals with sizes reaching the micrometer scale. Technical Parameter Composition Zn2+,C4H5N2- Status(white powder) Particle size 20 um Specific surface area ~1400 m2\/g Average pore size 0.34-1.16nm Pore volume 0.66 cm3\/g Product Features 1) Porosity: ZIF-8 features a high specific surface area and high porosity, which endows it with potential application value in fields such as adsorption, separation, and catalysis. 2) Adsorption performance: ZIF-8 exhibits excellent adsorption performance for various substances. For instance, it can efficiently adsorb trimethylamine, a typical fishy odor substance in seafood, with an adsorption capacity higher than that of commercial ZSM-5 molecular sieves, activated alumina, and activated carbon. 3) Superior biocompatibility: It does not cause damage to corneal endothelium or other tissues, which makes it have broad application prospects in the biomedical field. Application Fields 1) Drug delivery and biomedicine: ZIF-8 remains stable under physiological conditions but disintegrates in acidic conditions. This property makes it an ideal carrier for drug delivery. It can load drugs and release them at specific sites, enhancing therapeutic effects and reducing side effects. 2) Composite materials: ZIF-8 can be combined with other materials, such as gold nanoparticles and carbon nanofibers, to form composite materials with multiple functions. These composites exhibit superior performance in fields such as catalysis, sensing, and energy storage. 3) Energy storage: ZIF-8's high porosity and chemical stability make it a promising material for hydrogen storage. By adsorbing hydrogen, ZIF-8 can play a significant role in energy storage and conversion. 4) Sensor: The porous structure and chemical stability of ZIF-8 enable it to serve as the sensitive component of a sensor, capable of detecting various gases and chemical substances. Its high sensitivity and selectivity enable the sensor to be widely applied in fields such as environmental monitoring, industrial production, and biomedical research. 本公司销售的所有产品仅用于工业应用或者科学研究等非医疗目的,不可用于人类或动物的临床诊断或者治疗,非药用,非食用。 All products sold by our company are solely for industrial applications or scientific research and other non-medical purposes.
