  • About author:Jijie Wang (State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences) received his Ph.D degree in 2013 from Xiamen University. From 2013 to 2017, he did postdoctoral research at Dalian Institute of Chemical Physics (DICP), Chinese Academy of Sciences, his Co-supervisor is Professor Can Li. At the beginning of 2018, he joined the DICP, where he is now a professor of DICP. His researches mainly focus on catalytic hydrogenation of carbon dioxide to methanol, low carbon olefin, aromatic hydrocarbon, etc. He has made original achievements in the catalytic hydrogenation of carbon dioxide to methanol with high selectivity and stability, and developed ZnO-ZrO2 bimetal oxide solid solution catalyst to open up a new way for the hydrogenation of carbon dioxide. As one of the main contributors, he completed the world's first set of "liquid sunshine methanol" industrial pilot and demonstration projects. He has published 20 papers in Science Advances, Joule and other journals, applied for 14 domestic patents, and 2 international PCT patents. He has received Min Enze Energy and Chemical Industry Award-Youth Progress Award, International Catalytic Conference Young Scientist Award. He joined the editorial board of Chin. J. Catal. in 2020.

Abstract:

The conversion of CO2 to methanol with high activity and high selectivity remains challenging owing to the kinetic and thermodynamic limitations associated with the low chemical reactivity exhibited by CO2. Herein, we report a novel Cd/TiO2 catalyst exhibiting a methanol selectivity of 81%, a CO2 conversion of 15.8%, and a CH4 selectivity below 0.7%. A combination of experimental and computational studies revealed that the unique electronic properties exhibited by the Cd clusters supported by the TiO2 matrix were responsible for the high selectivity of CO2 hydrogenation to methanol via the HCOO* pathway at the interfacial catalytic sites.
