In recent years, research has focused on developing materials exhibiting outstanding mechanical, electrical, thermal, catalytic, magnetic and optical properties such as graphene/polymer, graphene/metal nanoparticles and graphene/ceramic nanocomposites. Two-dimensional sp hybridized graphene has become a material of choice in research due to the excellent properties it displays electrically, thermally, optically and mechanically. Noble nanomaterials also present special physical and chemical properties and, therefore, they provide model building blocks in modifying nanoscale structures for various applications, ranging from nanomedicine to catalysis and optics. The introduction of noble metal nanoparticles (NPs) (Au, Ag and Pd) into chemically derived graphene is important in opening new avenues for both materials in different fields where they can provide hybrid materials with exceptional performance due to the synergistical result of the specific properties of each of the materials. This review presents the different synthetic procedures for preparing Pt, Ag, Pd and Au NP/graphene oxide (GO) and reduced graphene oxide (rGO) composites.
近年来，研究主要集中在开发具有出色机械、电学、热学、催化、磁性和光学性能的材料，如石墨烯/聚合物、石墨烯/金属纳米颗粒和石墨烯/陶瓷纳米复合材料。二维sp杂化的石墨烯因其在电学、热学、光学和机械性能方面的优异表现，已成为研究中的首选材料。贵金属纳米材料也具有特殊的物理和化学性质，因此，它们为修饰纳米级结构提供了模型构建单元，可用于从纳米医学到催化和光学等各种应用。将贵金属纳米颗粒（NPs）（金、银和钯）引入化学衍生的石墨烯中，对于为这两种材料在不同领域开辟新途径非常重要，在这些领域中，由于每种材料的特定性能产生协同效应，它们可以提供具有卓越性能的混合材料。本文综述了制备铂、银、钯和金纳米颗粒/氧化石墨烯（GO）和还原氧化石墨烯（rGO）复合材料的不同合成方法。
