Abstract

The invention relates to a triple interpenetrating metal organic framework heterogeneous CO2 cycloaddition catalyst and a preparation method thereof, and application of a triple interpenetrating metalorganic framework heterogeneous CO2 cycloaddition catalyst, and belongs to the technical field of metal organic framework materials. Aiming at the defects of low activity, low stability and the likeof an existing CO2 cycloaddition reaction heterogeneous catalyst, the invention provides a triple interpenetrating metal organic framework heterogeneous CO2 cycloaddition catalyst, the molecular formula of the catalyst is [Zn(bbi)(tdc)]n5nH2O, in the formula, bbi represents 1,4-diimidazole butane, and tdc represents 2,5-thiophene dicarboxylate; the compound belongs to an orthorhombic system and aPnma space group, and is a triple interpenetrating three-dimensional framework. The composite catalyst composed of the catalyst and tetrabutylammonium bromide (TBAB) is used for heterogeneous CO2 cycloaddition catalysis, especially catalysis of heterogeneous CO2 and epoxy chloropropane cycloaddition reaction; and moreover, the composite molar ratio of the catalyst to tetrabutylammonium bromide is0.07:1.

Description

technical field [0001] The invention belongs to the technical field of metal organic framework materials. Background technique [0002] The rapid development of the oil industry has caused serious climate problems due to the extremely high concentration of carbon dioxide in the atmosphere. Therefore, in recent years, researchers have used CO 2 As a renewable C1 resource, more detailed research work has been carried out, and value-added chemical products have been prepared. Numerous CO 2 In the transformation pathway, CO 2 One of the most eco-friendly and atomically efficient routes to carbonates is the cycloaddition reaction with epoxides (abbreviation: CO 2 cycloaddition reaction). In the past 20 years, homogeneous catalysts (such as metal complexes, ionic liquids, organic catalysts, etc.) have accelerated the CO 2 Cycloaddition reactions have been extensively developed. However, the inherent low activity and low stability of heterogeneous catalysts greatly limit the...
