Umsebenzi okhoyo uxela inoveli inyathelo elinye, iprotocol eluhlaza yokwenziwa kwe-starch-stabilized palladium nanoparticles (PdNPs) kunye ne-particle diameter ye-30-40 nm.La masuntswana azinzile kwaye alinganayo ngobukhulu.Kwiprothokholi yangoku, ukuncitshiswa kwe-solar edibeneyo yokunciphisa i-palladium chloride kwaphunyezwa ngokusebenzisa i-citric acid njenge-agent yokunciphisa kunye ne-starch njenge-agent agent.I-UV-Visible spectroscopy, i-Transmission Electron Microscopy, i-Field Emission Gun-Scanning Electron Microscopy, Indawo ekhethiweyo ye-Electron Diffraction kunye ne-Electron dispersive X-ray ubuchule bokuhlalutya be-Spectral busetyenziselwe ukubonakalisa le PdNP ye-starch caped.Apha;sibika ukudibanisa okunjalo kwesitashi kunye ne-citric acid kwi-synthesis ye-PdNPs okokuqala.Umsebenzi we-catalytic we-nanoparticles eyenziwe yajongwa kwi-Suzuki kunye ne-Heck cross coupling reactions.Imveliso yemveliso yaqinisekiswa yiGC.Iimveliso zaqinisekiswa kusetyenziswa uhlalutyo lwe-GC-MS kunye nokusebenzisa i-GC kunye nemigangatho yokwenyani.Amandla elanga ancedise isitashi esizinzile iiPdNPs zibonise umsebenzi ogqwesileyo kwi-CC bond formation phakathi kwe-aryl halides (I, Br) kunye ne-phenyl boronic acid kunye ne-derivatives yayo.Ukongeza, i-catalyst ibonise umsebenzi omhle kwi-Heck coupling reaction ye-CC bond formation ye-aryl halides ene-alkene enuka kamnandi.Ukusetyenziswa kwesitatshi, i-citric acid, amanzi kunye namandla elanga kwenza inkqubo ekhoyo ngoku ibe luhlaza.
