Professor Wang Cheng, Xiamen University research group and collaborator: MOF supported Cu based catalyst for CO2 hydrogenation

Recently, Professor Wang Cheng's research group of Xiamen University has made progress in the use of MOF supported Cu based catalysts for CO 2 hydrogenation Relevant research results "cooperative copper centers in a metal – organizational framework for selective conversion of CO2 to enhance" were published online in nature catalyst (DOI: 10.1038 / s41929-019-0308-5) The hydrogenation of CO2 is considered to be an important direction of carbon resource recycling Among them, the direct hydrogenation of CO2 to ethanol is a valuable but challenging way The difficulty of ethanol synthesis lies in the regulation of C-C bond formation rate and C-O bond breaking rate in the hydrogenation process The rate imbalance will lead to the formation of single carbon products or long-chain alkanes The research group designed a MOF supported double copper center catalyst, which selected a metal organic framework with Zr 12 nodes（ MOFs) as the carrier, through the use of tmsli to deplasmize the hydroxyl groups on the nodes, and then add Cu source to the metal loaded post modification assembly technology to load the active center of Cui on the metal nodes, realize the construction of the metal center of bicu, which can not only activate hydrogen through the oxidation addition of bimetal, but also realize the formation of C-C bond with the assistance of alkali metal ions So as to realize the conversion of CO2 to ethanol This work not only shows the uniqueness of MOF as catalyst carrier, but also brings new understanding for the study of copper based catalyst for the hydrogenation of CO2 to ethanol The research work was completed by Professor Wang Cheng of Xiamen University and Professor Lin Wenbin of the University of Chicago Dr Li Zhe, 2014 Ph.D of Xiamen University (Ph.D.), and PhD student of PhD, 2016, are the first co authors Dr Zhang and Dr Zeng Ling participated in some work Dr Song Yang, a graduate student in University of Chicago, helped X- ray absorption spectroscopy data collection The research work was supported by the key R & D plan of the Ministry of science and Technology (approval No.: 2016yfa020702) and the National Natural Science Foundation (approval No.: 21671162, 21471126, 21721001).
