　　When singleatom meets 2D materials, many exotic physical and chemical properties emerge inthis hybrid system, which makes it highly desirable for a wide range ofapplications. In the first part of my talk, I will describe our recent scanningtunneling microscopy (STM) and atomic force microscopy (AFM) studies of singlemolecules/atoms on 2D materials with an aim to understand how the energylandscape of 2D materials can be modified by adsorbed single molecules/atoms.Moreover, 2D material surface can be chemically engineered to equip withdesirable functional groups, which thus offer an ideal platform for theanchoring of individual metal atoms as single atom catalysis (SACs). In thesecond part of my talk, I will discuss our recent work on the controllablesynthesis of graphene supported cobalt SACs (Co₁/G) with a tuneablehigh loading by atomic layer deposition. Our findings not only open up the newavenue for the investigation into charge transport through single molecules innanodevices but also pave the way for the precise engineering of metal atoms on2D materials for single atom catalysis.
