SynthesisofAg@Ccomplexes
VariousmethodshavebeendevelopedforsynthesizingAg@Ccomplexes,includingchemicalreduction,sol-gelprocess,hydrothermalsynthesis,electrochemicalsynthesis,andphotoreduction.Amongthemostwidelyusedmethodsarethechemicalreductiontechniqueandelectrochemicalsynthesis.
Inchemicalreductionmethods,silver(Ag)nanoparticlesarefirstpreparedbyreducingsilversaltswithareducingagentsuchassodiumcitrate,sodiumborohydride,orhydrazineinthepresenceofastabilizingagentsuchaspolyvinylpyrrolidone(PVP).Carbonsupportssuchasgrapheneoxide,multi-walledcarbonnanotubes,orcarbonblackarethenintroducedandmixedwiththeAgnanoparticlessolution,followedbyheatingundervacuumorinanoven,whichleadstoreductionoftheAgcationsontothecarbonsupportstoformtheAg@Ccomposite.
