Basa razvino rinoshuma riini nhanho imwe, yakasvibirira protocol ye synthesis ye starch-yakadzikama palladium nanoparticles (PdNPs) ine avhareji yechidimbu dhayamita ye30-40 nm.Zvimedu izvi zvakanga zvakagadzikana uye zvakafanana muhukuru.Muprotocol yazvino, kuderedzwa kwesimba rezuva kwakadzikiswa kwepalladium chloride kwakawanikwa nekushandisa citric acid sechinhu chinoderedza uye starch sechinhu chinovhara.UV-Visible spectroscopy, Transmission Electron Microscopy, Field Emission Gun-Scanning Electron Microscopy, Selected Area Electron Diffraction uye Electron dispersive X-ray Spectral analysis techniques akashandiswa kuratidza iyi starch capped PdNPs.Herein;isu tiri kuzivisa kusanganiswa kwakadaro kwe starch uye citric acid mukugadzirwa kwePdNPs kekutanga.Iyo inokonzeresa chiitiko che synthesized nanoparticles yakatariswa kune Suzuki uye Heck cross coupling maitiro.Chigadzirwa chacho chakasimbiswa neGC.Zvigadzirwa zvakasimbiswa uchishandisa GC-MS ongororo uye zvakare kushandisa GC neiyo lp yechokwadi zviyero.Simba rezuva rakabatsira starch yakagadzikana PdNPs yakaratidza basa rakanakisisa muCC bond formation pakati pe aryl halides (I, Br) ne phenyl boronic acid uye zvinyorwa zvayo.Mukuwedzera, iyo catalyst yakaratidza basa rakanaka muHeck coupling reaction yeCC bond kugadzirwa kwearyl halides ine anonhuwirira alkene.Kushandiswa kwe starch, citric acid, mvura uye simba rezuva kunoita kuti protocol yazvino isvibire.
