[Coal Chemical Industry] There are new ways for the green synthesis of MOF materials

During an interview with Xue Chunfeng, associate professor of the School of Chemistry and Chemical Engineering, Taiyuan University of Technology, it was learned that Xue Chunfeng's research team has made a major breakthrough in the preparation of metal organic framework material MOF-199, breaking the existing industrial synthesis of MOF-199 with low yield, many by-products, and waste liquid treatment.

In order to eliminate the influence of by-products on the yield of MOF-199, the research team proposed a strategy of indirect contact with by-products by introducing sodium hydroxide (AISB), and designed a sustainable no-waste emission synthesis pathway for MOF-199 .

According to Xue Chunfeng, in the synthesis system, sodium hydroxide can well capture and fix the by-products volatilized from the reaction system, which enhances the dynamics of the entire reaction process, thereby obtaining a higher yield.

"MOF-199 is formed by the coordination polymerization of trimellitic acid and copper nitrate.

In order to meet the above challenges, Xue Chunfeng’s research team designed a strategy to indirectly induce the transfer of by-products in alkali based on the previous accumulation in the green synthesis of porous functional materials, which achieved the high-capacity synthesis of MOF-199 and its dry-based yield.

"Through further technical research, the team has completed the MOF scale-up experiment in the laboratory, laying the foundation for realizing a ton-level daily production capacity.

As an important new type of porous material, MOF materials are widely used in catalysis, energy storage and separation.
