Embodiment 1

[0035] A preparation method of a flavone derivative-zinc complex, comprising the following steps:

[0036] S1. Mix N,N-dimethylformamide and methanol with a volume ratio of 3:1 to obtain a reaction solvent;

[0037] S2. get 4.90mg of 3-hydroxyl-6,4'-flavone dicarboxylic acid, 4.50mg of Zn(NO 3 ) 2 2.5H 2 The reaction solvent of O and 2mL mixes, and packs into glass tube and vacuum seals, obtains reactant;

[0038] S3. Put the reactants in an oven, raise the temperature of the oven from room temperature to 90°C within 300 minutes, and keep it at 90°C for 5000 minutes, then lower the temperature from 90°C to 30°C within 600 minutes, and finally cut the glass tube, light yellow blocky crystals were obtained;

[0039] S4. The light yellow blocky crystals were washed with N,N-dimethylformamide and dried in vacuum to obtain a complex with a yield of 65%.

Abstract

The invention relates to the field of material synthesis, and discloses a flavone derivative-zinc complex and a preparation method thereof. The preparation method comprises the following steps: S1, taking N, N-dimethylformamide and methyl alcohol and mixing, and obtaining a reaction solvent; S2, taking 3-hydroxy-6, 4 '-flavone dicarboxylic acid, a zinc salt crystal and the reaction solvent, mixing, and sealing to obtain a to-be-reacted substance; S3, sequentially carrying out heating, heat preservation and cooling treatment on the to-be-reacted substance to obtain yellow blocky crystals; and S4, washing and drying the yellow blocky crystals to obtain the complex. The invention also discloses an application of the complex in capturing and converting CO2 under normal pressure. The complex has a unique open Zn site and a smooth pore channel structure and can adsorb a large amount of CO2 at normal temperature and serves as a Lewis acid catalyst to become a nano reactor for reacting CO2 with an epoxy compound at normal temperature and normal pressure to generate cyclic carbonate; meanwhile, due to the high stability of the Zn site, the complex has excellent recovery performance in the catalytic reaction and separation process.

Description

technical field [0001] The invention relates to the field of material synthesis, in particular to a flavone derivative-zinc complex and a preparation method and application thereof. Background technique [0002] 85% of the energy needed for human life comes from the combustion of fossil fuels. As a non-renewable resource, fossil fuels will face depletion in a few decades as their reserves decrease. Therefore, the society's demand for renewable resources Seeking is especially urgent. On the other hand, as the main greenhouse gas, increasing carbon dioxide in the atmosphere has caused serious climate change in recent decades. However, carbon dioxide is a good renewable resource, so in order to reduce carbon dioxide emissions, it is also an urgent task to develop feasible carbon dioxide capture and storage technologies. [0003] Currently, amine-based wet scrubbing systems have been used industrially to capture and store CO2, but its high energy cost, strong corrosion, and lo...
