Problems solved by technology

These materials are in CO 2 and H 2 Great progress has been made in the storage of etc. (CO 2 Adsorption capacity 8.0~12.0%, H 2 The adsorption capacity is 0.5-1.8%), but these materials face a common key problem, that is, due to the weak interaction between the organic adsorbent framework and the adsorbed molecules, especially for small molecular gases such as CO 2 and H 2 The adsorption capacity is still very low, which cannot meet the requirements of practical application.
Although metal-organic framework materials MOFs have better adsorption performance, they have poor thermochemical stability
Although the use of metal-doped organic microporous polymers can significantly increase the volume adsorption fraction, but the nano-metal ions are easy to agglomerate and reduce the weight adsorption fraction

Embodiment 1

[0038] In a 250mL three-neck flask equipped with mechanical stirring, a reflux condenser and a constant pressure dropping funnel, add 6 parts of triazine chloride, 20 parts of methanesulfonic acid, and 90 mL of o-dichlorobenzene in sequence. After reacting for 2 hours, 40 mL of o-dichlorobenzene solution dissolved in 9 parts of ferrocene was added dropwise, and the temperature was raised to 180° C. and refluxed for 12 hours. After the reaction solution is cooled, the resulting precipitate is collected by filtration, washed with alcohol, acid washed, extracted with THF, and dried to obtain the product. The sample is heated to 180-200° C. for 8 hours under vacuum condition (10 kPa) to activate the ferrocene-based polymer porous material.

Abstract

The invention discloses a ferrocenyl polymer and a porous material thereof, and preparation methods and application thereof. According to the invention, ferrocene and a trihalogenated compound or triacyl chloride are subjected to a Friedel-Craft reaction so as to obtain the ferrocenyl polymer; the ferrocenyl polymer is further activated so as to obtain the polymer porous material. The ferrocenyl polymer porous material has a high specific surface area, a great pore volume and a stable structure, is applied to a great number of fields like catalyst carriers, storage and capture of gas, deep treatment of metal ions and separation of harmful steam of aromatic compounds and shows good adsorptivity on gas molecules like CO2, H2, HCHO and benzene steam. The preparation methods for the polymer and the porous material thereof are simple, convenient and easily practicable and suitable for industrial production.

Description

technical field [0001] The invention relates to ferrocene-based polymers and porous materials, their preparation methods and applications, belonging to the field of polymer materials. Background technique [0002] In the case of environmental pollution and depletion of fossil fuels, it is imminent to develop new energy sources and control the greenhouse effect, so gas molecules such as CO 2 and H 2 The capture and storage of fish, etc. is of great significance to the sustainable development of our country's economy. Using nanoporous materials to adsorb gas molecules such as CO 2 and H 2 Or the separation and enrichment of heavy metal ions is one of the hottest topics in the field of materials, energy and environmental research, and has particularly important academic value and industrial application value. [0003] Polymer materials with nanoporous properties have broad application prospects in adsorption, separation, and carrier materials due to their abundant raw mater...
