报 告 内 容: 

Carbon oxygen (C-O) bond is common in polyols, acids, ethers, esters, which can be derived from biomass and syngas-related chemicals. Selective hydrogenolysis of C-O bonds is one of the most important catalytic reactions involving these species containing C-O bond to produce hydrocarbon fuels, alcohols, and other bulk or fine chemicals. Copper (Cu)-based catalysts have been extensively used in hydrogenolysis of C-O bonds due to its regioselectivity under mild reaction conditions. Because of the low Hütting temperature, Cu nanoparticles are easy to aggregate into large particles. In addition, the reaction conditions for hydrogenolysis of C-O bonds are normally harsh requiring high pressure of H2 and high temperature. Cu+ and Cu0 species, generally recognized as the active species for Cu catalysts, can hardly keep in balance under the redox atmosphere of C-O bond hydrogenolysis. These factors lead to low activity and less stability of Cu catalyst. Herein, strategies to enhance Cu catalytic performance are presented. Dimethyl oxalate hydrogenation, which is an important step of syngas-to-ethylene glycol, is used as the typical example of C-O bond hydrogenolysis. Several Cu catalysts modified with structural and /or electronic promoters are developed to boost the Cu catalysis. As a result, a new route for syngas-to-ethylene glycol is achieved. Combined with advanced characterization techniques, the role of these promoters to Cu is elucidated and structure-performance relationship is established.
