Abstract

The invention discloses a metal organic framework catalyst as well as a preparation method and application thereof. The preparation method comprises the following steps: 1) synthesizing a ligand, namely tetrakis(4-carboxyl)terphenyl methane; 2) synthesizing the metal organic framework catalyst constructed by an organic ligand and a metal cluster; and 3) calculating the efficiency of the catalytic phospholipid compound and exploring related mechanisms. According to the invention, an inorganic-organic hybridization strategy is adopted, and a high-pore catalyst is synthesized based on the advantages of a metal organic framework material. An adopted organic hybridization strategy can reduce the content of metal and improve the biological compatibility of catalysis; and a high-pore structure can improve the adsorption contact capacity of the catalyst and guest molecules and improve the catalytic efficiency, so performance optimization is achieved.

Description

technical field [0001] The invention relates to the technical field of catalyst material synthesis, in particular to a metal-organic framework catalyst, a preparation method, and an application. Background technique [0002] Phospholipid bonds are very common in living organisms, such as DNA, RNA, phospholipidated proteins, and ATP. Catalyzing the hydrolysis of phospholipid bonds can regulate the activity of proteins and the stability of DNA and RNA, further enabling the development of different therapeutic methods. Therefore, designing and synthesizing catalysts that catalyze phospholipid bonds is of great significance in the field of biomedicine. [0003] It has been reported that the catalysts capable of catalyzing the hydrolysis of phospholipid bonds are inorganic nanoparticles or small molecular compounds, such as: cerium oxide nanoparticles (M.H.Kuchma, C.B.Komanski, J.Colon, A.Teblum, A.E.Masunov, B.Alvarado, S.Babu, S.Seal, J.Summy, C.H.Baker, Nanomed.Nanotechnol.,...
