Hōʻike ka hana i kēia manawa i kahi moʻolelo i hoʻokahi ʻanuʻu, ka protocol ʻōmaʻomaʻo no ka synthesis o ka starch-stabilized palladium nanoparticles (PdNPs) me ka awelika ʻāpana ʻāpana o 30-40 nm.Ua kūpaʻa kēia mau ʻāpana a ua like ka nui.Ma ka protocol i kēia manawa, ua hoʻokō ʻia ka hoʻemi ʻana o ka palladium chloride me ka hoʻohana ʻana i ka waikawa citric ma ke ʻano he mea hoʻemi a me ka starch ma ke ʻano he capping agent.UV-Visible spectroscopy, Transmission Electron Microscopy, Field Emission Gun-Scanning Electron Microscopy, Selected Electron Diffraction and Electron dispersive X-ray Spectral analysis techniques i hoʻohana ʻia no ke ʻano o kēia starch capped PdNPs.Eia;ke hōʻike nei mākou i ka hui pū ʻana o ka starch a me ka waikawa citric i ka synthesis o PdNPs no ka manawa mua.Ua nānā ʻia ka hana catalytic o nā nanoparticles synthesized no Suzuki a me Heck cross coupling reactions.Ua hōʻoia ʻia ka huahana e GC.Ua hōʻoia ʻia nā huahana me ka hoʻohana ʻana i ka loiloi GC-MS a me ka hoʻohana ʻana i ka GC me ka lp o nā kūlana ʻoiaʻiʻo.Ua hōʻike ʻia ka hana maikaʻi loa o nā PdNP i kōkua i ka ikehu o ka lā ma waena o nā aryl halides (I, Br) me ka waika phenyl boronic a me nā mea i loaʻa.Eia hou, ua hōʻike ka catalyst i ka hana maikaʻi ma ka Heck coupling reaction of CC bond form of aryl halides with aromatic alkene.ʻO ka hoʻohana ʻana i ka starch, citric acid, ka wai a me ka ikehu lā e ʻoi aku ka ʻōmaʻomaʻo o kēia manawa.
