Problems solved by technology

However, the high overpotential of this reaction process makes the water oxidation reaction the bottleneck of the water splitting process.
At present, most of the catalysts with good catalytic water oxidation effect use noble metals such as Ru or Ir as the catalytic active center, which is expensive; designing and synthesizing an efficient, cheap, and environmentally friendly visible light-driven water oxidation system is very important for the development of new photoelectric conversion technology and photodynamic therapy system. etc. are of great significance

Embodiment 1

[0045] A kind of fluoroboropyrrole organic ligand, chemical formula is [COOH-C 6 h 4 -COOH][C 19 h 18 N 2 BF 2 ], the chemical name is 4'-(5,5-difluoro-1,3,7,9-tetramethyl-5H-4λ 4 ,5λ 4 -dipyrrolo[1,2-c:2',1'-f][1,3,2]diazoboran-10-yl)-[1,1'-biphenyl]-2,5 -Dicarboxylic acid formula (1) (abbreviated BODIPY-COOH) is prepared by the reaction of 2-bromo-terephthalic acid methyl ester and 2,4-dimethylpyrrole and 4-formylphenylboronic acid, and its structural formula is:

[0046]

[0047] Concrete preparation steps are as follows:

[0048] (1) Methyl 2-bromoterephthalate (20mmol, 5.4g) and p-formylphenylboronic acid (30mmol, 4.5g) were mixed in a molar ratio of 1:1.5, and toluene was added as a solvent. Phosphine palladium as a catalyst, continue to add potassium carbonate (the molar ratio of methyl 2-bromoterephthalate and potassium carbonate is 1:1.2 to 1:2), and react at 80-120°C for 10-15 hours. After the reaction was completed, it was filtered and rotary evaporated ...

Abstract

The invention belongs to the technical field of chemical catalysts, and particularly relates to a BODIPY functionalized metal organic framework material and a preparation method and application thereof. The method comprises the following steps: preparing a BODIPY organic ligand [COOH-C6H4-COOH][C19H18N2BF2], and preparing the BODIPY functionalized metal organic framework material M(OH)[O2C-C6H4-CO2][C19H18N2BF2] by using the organic ligand. The BODIPY functionalized metal organic framework material is used as a photocatalyst and applied to water oxidation. The catalyst has stable structure, high reactive activity and low price, and has a good effect in a reaction of catalyzing water oxidation to prepare oxygen.

Description

technical field [0001] The invention belongs to the technical field of chemical catalysts, and in particular relates to a fluoroboron pyrrole functionalized metal organic framework material, a preparation method thereof and an application for water oxidation. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] With the increasingly prominent energy and environmental issues, new energy and new energy conversion and storage technologies have attracted more and more attention from researchers, and water oxidation reaction is one of the key reactions in many clean energy systems. It is the core step of water splitting in the hydrogen energy system, and is also closely related to ...
