Noble metal nanoparticles (NMNPs) like silver (Ag), copper (Cu), palladium (Pd), and gold (Au) have enhanced potential to improve energy storage capacity of supercapacitors. The unique characteristics of NMNPs, like their high conductivity, wide area of surface, and outstanding catalytic activity can result in significant increases in electrochemical performance when integrated with graphene-based and molybdenum (Mo)-based supercapacitors. The cooperative actions of NMNPs enhance capacitance and energy density while facilitating effective charge transfer, which is advantageous for graphene-based supercapacitors. The addition of NMNP can also lead to increased electrochemical activity and better cycle stability in Mo-based supercapacitors, which are renowned for their high theoretical capacitance and stability. Cu, Pd, Ag, and Au nanoparticles all have unique benefits to offer: Pd has excellent catalytic performance, Ag has great electrical conductivity, Au has exceptional chemical stability, and Cu is reasonably priced. It appears that in order to improve the structural and functional features of NMNPs for better supercapacitor performance, hybrid materials combining them with graphene and Mo compounds will be developed in the future. Additionally, improvements in synthesis and nanostructuring techniques will probably improve NMNP integration and functioning in supercapacitors even more, opening door to develop high-performance energy storage devices of the next generation.
