A series of progress in the catalytic conversion of CO2 over the ionic MOFs catalysts of Cao Rong and Huang yuanbiao from Fujian Institute of physical structure

Transforming CO2 into high value-added chemicals is a long-term challenge for human beings The current MOFs catalysts usually need high pressure or a large number of cocatalysts (such as organic base as nucleophilic reagent), which not only increases the risk and cost, but also may block the pore and reduce the catalytic activity Therefore, Cao Rong and Huang yuanbiao, State Key Laboratory of structural chemistry, Fujian Institute of physical composition, Chinese Academy of Sciences Under the support of the key research and development plan of the Ministry of science and technology, the National Natural Science Foundation project, the strategic leading science and technology project of the Chinese Academy of Sciences and the key research project of cutting-edge science, the team created a series of cationic imidazolium salts functional MOFs catalytic materials based on the strategy of "inorganic organic active radical synergistic catalysis": self-assembly of imidazolium functionalized linear carboxylic acid ligands and Zr ions The nano scale Zr based MOF catalytic material (chem SCI 2017, 8, 1570) was obtained; the porphyrin zinc / imidazolium salt multifunctional unit Zr based MOF catalytic material (inorg Chem 2018, 57, 2584 – 2593) was obtained by using the mixed ligand direct method; the mesoporous ion type bifunctional Cr based MOF material (chem Commun 2018, 54, 342 – 345 inner cover) Due to the synergistic action of Bronsted acid site (Zr-OH) or Lewis acid site (CR) on the MOFs framework and imidazolium salt anion on the MOFs framework, the reaction of olefin epoxide and CO2 to cyclic carbonate can be realized under the condition of solvent-free and atmospheric pressure without the need of cocatalyst, and the series of catalysts can be recycled for many times This series of work provides a green way to realize the catalytic conversion of CO2 under atmospheric pressure without the addition of cocatalyst On this basis, he was invited to systematically summarize and look forward to the work of MOFs and porous organic polymer materials catalyzing CO2 cycloaddition reaction to obtain cyclic carbonate on coord Chem Rev (DOI: 10.1016 / j.ccr 2017.11.013) In addition, the team also prepared high-efficiency porous organic polymers (chem Commun 2016, 52, 13288), porous covalent triazine framework materials (chemcatchem, DOI: 10.1002/cctc.201800023; catalyst SCI Technol, DOI: 10.1039/c8cy00176f) catalysts, which can transform CO2 cycloaddition and photoreduction catalysis into high value-added chemicals Corresponding author: researcher Cao Rong, researcher Huang yuanbiao
