  • About author:Ning Yan (Department of Chemical & Biomolecular Engineering, National University of Singapore) currently holds a Dean’s Chair Professorship at National University of Singapore. He received his B.Sc. and Ph.D. degrees in chemistry from Peking University (China) in 2004 and 2009, respectively (supervisor: Prof. Yuan Kou). Then he joined the École Polytechnique Fédérale de Lausanne in Switzerland with a Marie Curie Fellowship until 2012 (collaborator: Prof. Paul Dyson). After that, he started working in the Department of Chemical and Biomolecular Engineering in National University of Singapore and was promoted to a tenured associate professor in 2018. He received NRF Investigatorship Award (2022), NUS Young Researcher Award (2019), ACS Sustainable Chemistry & Engineering Lectureship Award (2018), and RSC Environment, Sustainability and Energy Early Career Award (2017), among others. His research interests lie in advanced heterogeneous catalysis, green chemistry & engineering, and renewable energy & chemical production, with over 200 published peer-reviewed papers.
    Tao Zhang (Dalian Institute of Chemical Physics, Chinese Academy of Sciences) received his Ph.D. in physical chemistry from Dalian Institute of Chemical Physics (DICP) in 1989 under the supervision of Prof. Liwu Lin. After a one-year postdoctoral position with Prof. Frank Berry at Birmingham University, he founded his own group at DICP in 1990 and promoted to full professor there in 1995. Prof. Zhang was the director of DICP in 2007-2017 and has been a vice president of Chinese Academy of Sciences since 2017. He was appointed as the editors-in-chief of Chin. J. Catal. in 2014. Meanwhile, he has been the director representing the China aside of the China-France Joint laboratory for Sustainable Energy since 2008. Prof. Zhang has won many important awards, such as the National Invention Prize (for three times), Distinguished Award of CAS, Excellent Scientist Award of Chinese Catalysis Society, and Ho Leung Ho Lee Prize for Science and Technology. His research interests focus on heterogeneous catalysis, environmental catalysis, and biomass conversion. He authored and coauthored more than 400 publications in peer-reviewed journals.

Abstract:

This perspective assesses the recent progress using single-atom catalysts for five “holy grail” reactions, including partial methane oxidation to methanol, non-oxidative methane conversion, photocatalytic CO2 reduction, photocatalytic water splitting, and nitrogen activation. Using selected case studies, we discuss promising efforts in these domains and at the same time identify the remaining challenges in using SACs for selective and efficient chemical transformations across thermal, electrical, and light-driven catalysis. Looking forward, we highlight the significant potential of SAC research in areas like mechanistic studies, high-throughput screening, and novel catalytic system design.
