Preparation Of Porous Materials And Research On Catalytic Properties

Covalent organic framework compounds are composed of light elements C,O,N,B,etc.,which are connected by covalent bonds.The thermodynamically controlled ordered porous crystalline materials formed by reversible polymerization are currently a hot area in materials science research.In this paper,we synthesized a micron-sized COF-ASB using 1.3.5-polyacylaminourea benzene and 1.4-terephthalaldehyde,and prepared a Ru@COF-ASB catalyst using it loaded with precious metal Ru nanoparticles.The obtained composite material is able to highly promote one-pot tandem synthesis of imine products from benzyl alcohols and corresponding amines under solvent-free conditions in air.The metal organic frameworks are obtained through the coordination of metal elements and inorganic non-metallic elements,which are also hot topics in the current scientific research of materials.?.Using 1.3.5-polyacylaminourea benzene and terephthalaldehyde as raw materials,a COF-ASB with a micron size was synthesized and its structure was measured.Subsequently,the noble metal nanoparticles were adsorbed by the covalent organic framework compound.Catalyst Ru@COF-ASB was obtained.The catalytic properties of the catalyst were then investigated.?.We used the Cu(?)-MOF adsorb Ru metal nanoparticles in acetonitrile solution to obtain a Ru@MOF catalyst,which was used to catalyze the oxidation reaction of benzyl alcohol.
