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.
