Abstract : 
Catalytic CO2 reduction reaction (CO2RR) driven by solar or renewable energy has attracted extensive attention due to its potential role in mitigating green-house effect and energy crisis. However, due to the extremely stable chemical bond in CO2, the competing hydrogen evolution reaction in the presence of water, as well as the reduction of CO2 involving a multi-electron stepwise process with several intermediates generated from different chemisorbed species, the design of highly efficient and selective catalysts for CO2RR, especially to produce hydrocarbons, is challenging. 

In this seminar, our investigations on the design and modification of MOFs for photo- and electro-catalytic CO2RR to give products of CO, CH4, acetate, and C2+ hydrocarbons will be presented, focusing on the importance of coordination and supramolecular interactions between the active site with CO2 and intermediates, rational integration of photosensitizers with CO2 reduction centers for the catalytic activities and selectivities, as well as rational integration of dual metal active sites for the production of ethylene and other high value-added C2+ compounds.

About the Speaker : 
Xiao-Ming Chen received his Ph.D (1992) from The Chinese University of Hong Kong. He joined the Chemistry Faculty at SYSU in 1992, and was promoted as a professor in 1995. He is member of the Chinese Academy of Sciences (since 2009), Fellow of The World Academy of Sciences for Advancement of Science in Developing Countries (TWAS, since 2013). His research interests include synthesis, structures and properties of functional coordination polymers (including metal-organic frameworks, i.e. MOFs) and metal complexes, especially for the porous and electric/magnetic coordination materials. He was the first to discover several zinc imidazolates with permanent zeolitic MOF structures including MAF-4 (well-known as ZIF-8), before the term of ZIFs appeared, which has then become the most well-known MOF.

He has published more than 520 papers including Science, JACS, Angew Chemie, Nature Comm, Adv Materials, Natl Sci Rev, Acc Chem Res, Chem Soc Rev, and Chem Rev. His publications have currently received more than 46,000 citations with an H-index >116 in Web of Science. He has won a number of prestigious science awards, including China National Natural Science Prize in 2007, TWAS prize in Chemistry in 2012, Khwarizmi International Award (2020), International Award of Japan Society of Coordination Chemistry (JSCC, 2020).
