Cov haujlwm tam sim no qhia txog ib kauj ruam tshiab, cov txheej txheem ntsuab rau kev sib txuas ntawm cov hmoov txhuv nplej siab-stabilized palladium nanoparticles (PdNPs) nrog qhov nruab nrab particle txoj kab uas hla ntawm 30-40 nm.Cov khoom no tau ruaj khov thiab tsis sib xws hauv qhov loj.Nyob rau hauv cov txheej txheem tam sim no, lub hnub ci zog ua kom sib haum xeeb txo qis ntawm palladium chloride tau ua tiav los ntawm kev siv citric acid ua tus neeg sawv cev txo qis thiab cov hmoov txhuv nplej siab ua tus neeg sawv cev capping.UV-Visible spectroscopy, Transmission Electron Microscopy, Field Emission Gun-Scanning Electron Microscopy, Selected Area Electron Diffraction and Electron dispersive X-ray Spectral analysis techniques are used to characterize this starch capped PdNPs.Ntawm no;peb tau tshaj tawm xws li kev sib xyaw ntawm cov hmoov txhuv nplej siab thiab citric acid hauv kev sib xyaw ntawm PdNPs thawj zaug.Cov kev ua haujlwm catalytic ntawm synthesized nanoparticles tau raug kuaj xyuas rau Suzuki thiab Heck cross coupling cov tshuaj tiv thaiv.Cov khoom lag luam tau lees paub los ntawm GC.Cov khoom tau lees paub siv GC-MS tsom xam thiab tseem siv GC nrog nws lp ntawm cov qauv qhabnias.Hnub ci zog pab cov hmoov txhuv nplej siab ruaj khov PdNPs tau pom zoo ua haujlwm hauv CC daim ntawv cog lus tsim ntawm aryl halides (I, Br) nrog phenyl boronic acid thiab nws cov derivatives.Tsis tas li ntawd, cov catalyst tau pom zoo ua haujlwm hauv Heck coupling cov tshuaj tiv thaiv ntawm CC daim ntawv cog lus tsim ntawm aryl halides nrog aromatic alkene.Kev siv cov hmoov txhuv nplej siab, citric acid, dej thiab hnub ci zog ua rau cov txheej txheem tam sim no ntsuab.
