Panopa ntchito lipoti buku sitepe imodzi, wobiriwira protocol kwa synthesis wa wowuma-okhazikika palladium nanoparticles (PdNPs) ndi pafupifupi tinthu awiri a 30-40 nm.Tinthu tating'ono ting'onoting'ono tating'onoting'ono tating'onoting'ono komanso tofanana.Mu ndondomeko yamakono, kuchepetsedwa kwa mphamvu ya dzuwa kwa palladium chloride kunatheka pogwiritsa ntchito citric acid monga kuchepetsa ndi wowuma ngati capping agent.UV-Visible spectroscopy, Transmission Electron Microscopy, Field Emission Gun-Scanning Electron Microscopy, Selected Area Electron Diffraction ndi Electron dispersive X-ray Spectral kusanthula njira zinagwiritsidwa ntchito pozindikira wowuma wopangidwa ndi PdNPs.Apa;Tikunena za kuphatikiza kotere kwa wowuma ndi citric acid mu kaphatikizidwe ka PdNPs koyamba.The chothandizira ntchito ya nanoparticles apanga wakhala kufufuzidwa kwa Suzuki ndi Heck mtanda lumikiza zimachitikira.Zokolola zogulitsa zidatsimikiziridwa ndi GC.Zogulitsazo zidatsimikiziridwa pogwiritsa ntchito kusanthula kwa GC-MS komanso kugwiritsa ntchito GC ndi miyezo yodalirika.Dzuwa mphamvu anathandiza wowuma okhazikika PdNPs anasonyeza ntchito kwambiri mu CC chomangira mapangidwe pakati aryl halides (I, Br) ndi phenyl boronic asidi ndi zotumphukira zake.Kuonjezera apo, chothandizira chinasonyeza ntchito yabwino mu Heck coupling reaction ya CC bond mapangidwe a aryl halides ndi alkene onunkhira.Kugwiritsiridwa ntchito kwa wowuma, citric acid, madzi ndi mphamvu yadzuwa kumapangitsa kuti ndondomekoyi ikhale yobiriwira.
