Multifaceted Applications of Nanoparticle Functionalized Graphene

Recently, graphene sheets have attracted a huge awareness for their special optical, mechanical, magnetic, electronic, and thermal characteristics. This has been possible due to the thin yet robust two-dimensional structural arrangement. The special properties may further be enhanced by smart chemical modifications on the twodimensional structure. Meanwhile, nanoparticles also have come up as an emerging platform for their size, shape, surface area, optoelectronic properties and flexibility in functionalization. To utilize the advantages of both worlds, the scientific community has combined graphene with metallic nanoparticles. This event has brought about extreme enhancements in the above properties. Both inorganic and organic nanoparticles have been attached to the graphene surface. However, the attachment of metallic nanoparticles has increased their applications in developing sensors and catalysts. In this literature review, we want to concentrate on synthesizing and functionalizing graphene with different metallic nanoparticles. At the same time, we would discuss their applications in various fields.
