| Summary: | <p> Two dimensional (2D) atomic layered nanomaterials exhibit some of the most striking phenomena in modern materials research and hold promise for a wide range of applications including energy and biomedical technologies. Graphene has received much attention for having extremely high surface area to mass ratio and excellent electric conductivity. Graphene has also been shown to maximize the activity of surface-assembled metal nanoparticle catalysts due to its unique characteristics of enhancing mass transport of reactants to catalysts. As an alternative, bismuth selenide has been recognized for its advanced electronic and optical properties. Our research specifically targets the preparation of gold nanoparticles supported on 2D nanomaterials, graphene oxide and bismuth selenide nanosheets, using the strategy of pre-formed nanoparticle self-assembly and aims at understanding the interactions between ligand-capped gold nanoparticles and different nanosheets. By varying the functional groups on the ligands between alkyl, aromatic, amine, and alcohol groups, different interactions such as van der Waals, ?-? stacking, dipole-dipole, and hydrogen bonding are investigated.</p><p>
