When single atoms and single molecules meet 2D materials, many exotic physical and chemical properties emerge in this hybrid system, which makes it highly desirable for a diversity of applications ranging from nanoelectronics and catalysis,. In the first part of my talk, I will describe our recent work on single molecules/atoms on 2D materials with an aim to understand how the energy landscape of 2D materials can be modified by adsorbed single molecules/atoms. Moreover, 2D material surface can be chemically engineered to equip with desirable functional groups, which thus offer an ideal platform for the anchoring of individual metal atoms as single atom catalysis (SACs). In the second part of my talk, I will discuss our recent work on the controllable synthesis of graphene supported cobalt SACs (Co1/G) with a tuneable high loading by atomic layer deposition. Our findings not only open up the new avenue for the investigation into charge transport through single molecules in nanodevices but also pave the way for the precise engineering of metal atoms on 2D materials for single atom catalysis.

Dr. Jiong Lu is currently an assistant professor at Department of Chemistry, Centre for Advanced 2D Materials, at National University of Singapore (NUS). He received his Bachelor’s degree from Fudan University (China) in 2007 and Ph.D. degree from NUS in 2011. After that, he worked as a postdoc fellow in Graphene Research Centre, NUS and then joined Mike Crommie’s group at Department of Physics, UC, Berkeley for his postdoctoral research. His current research interests include atomic-scale imaging and characterization of 2D materials and their gate-tunable devices, single-atom and clusters catalysis for energy related applications. He has published 50 peer-reviewed papers including Nature nanotechnology (2), Nature Materials (1), Nature Communications (8), Science Advances (2). His publications have received over 3700 citations.
