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. This paper specifically investigates the strategy of pre-formed nanoparticle self-assembly used for the formation of various metal nanoparticles supported on graphene families such as graphene, graphene oxide, and reduced graphene oxide and aims at understanding the interactions between ligand-capped metal nanoparticles and 2D nanomaterials. By varying the functional groups on the ligands between alkyl, aromatic, amine, and alcohol groups, different interactions such as van der Waals, π-π stacking, dipole-dipole, and hydrogen bonding are formed as the 2D hybrids produced.
二维（2D）原子层状纳米材料展现出现代材料研究中一些最为显著的现象，并在包括能源和生物医学技术在内的广泛应用领域具有潜力。石墨烯因其极高的比表面积和出色的导电性而备受关注。由于石墨烯具有增强反应物向催化剂传质的独特特性，它还被证明能使表面组装的金属纳米颗粒催化剂的活性最大化。本文具体研究了用于形成负载在石墨烯家族（如石墨烯、氧化石墨烯和还原氧化石墨烯）上的各种金属纳米颗粒的预成型纳米颗粒自组装策略，旨在了解配体封端的金属纳米颗粒与二维纳米材料之间的相互作用。通过改变配体上的官能团，使其在烷基、芳基、胺基和醇基之间变化，随着二维杂化材料的产生，会形成不同的相互作用，如范德华力、π-π堆积、偶极-偶极相互作用和氢键。
