Abstract

The invention discloses a triazinyl porous polymer material. The triazinyl porous polymer material is an acetylene bond-functionalized triazinyl porous polymer. The invention also relates to an application of an Ag/triazinyl porous polymer catalyst in catalysis of a carboxylation reaction of the aromatic terminal alkyne and CO2. The triazinyl porous polymer material with high CO2 adsorption capacity is designed and synthesized, and Ag nanoparticles are loaded through using the coordination characteristic of a triazine ring in order to introduce a catalytic active unit to the triazinyl porous organic material skeleton and obtain the Ag/triazinyl porous polymer catalyst. The catalyst can catalyze the direct carboxylation of the aromatic terminal alkyne and CO2 to synthesize acetylenic acid, that is, the catalyst converts CO2 into a chemical substance with high added values.

Description

technical field [0001] The invention relates to a triazine-based porous polymer material, an Ag / triazine-based porous polymer catalyst and the application thereof for converting carbon dioxide into alkynoic acid. Background technique [0002] With climate warming and the increasing energy crisis, CO 2 The capture and transformation of carbon dioxide have attracted widespread attention from the international community. As a new type of porous material, organic framework materials are widely used in CO due to their advantages such as low framework density, high specific surface area, and modifiable framework. 2 Adsorption and separation fields have broad application prospects. Using organic framework materials as adsorbents to capture and convert CO in situ with high efficiency and low energy consumption 2 As a high value-added chemical, it has important scientific value and theoretical significance for mitigating the greenhouse effect and resource utilization. [0003] In...
