Noble zitsulo nanoparticlesakhala bwino ntchito monga chothandizira mu hydrogenation mkulu maselo kulemera ma polima.Mwachitsanzo, rhodium nanoparticle/nanopowders asonyeza ntchito kwambiri ndi selectivity wabwino mu hydrocarbon hydrogenation.

Olefin double bond nthawi zambiri imakhala pafupi ndi gulu lalikulu la ntchito-hydrocarbon gulu, zomwe zimapangitsa kuti zikhale zovuta kutsegula mgwirizano wapawiri.Ndi kuwonjezera kwa 20nm rhodium ufa, ndikosavuta kutsegula chomangira chapawiri ndikupanga hydrogenation reaction bwino.

Olefins omwe amatha kupangidwa ndi nano rhodium akuphatikizapo 1-hexene, cyclohexene, 2-hexene, butenone, mesityl oxide, methyl acrylate, methyl methacrylate, ndi cyclooctene, pakati pa ena.Kukula kwa tinthu kosiyanasiyana kumakhudza ntchito yothandiza.Nthawi zambiri, ang'onoang'ono ndi tinthu kukula, mofulumira ndi hydrogenation mlingo.

Henan Normal University ndi Institute of Chemistry, Chinese Academy of Sciences agwirizana kuti apange njira yatsopano ya asymmetric catalytic synthesis ya kalasi ya chiral acyclic nucleoside compounds.Pogwiritsa ntchito zovuta zopangidwa ndi nano rhodium (Rh) ndi chiral bisphosphine ligand (R) -BINAP monga chothandizira, mndandanda wa maunyolo am'mbali adakonzedwa ndi asymmetric hydrogenation ya α-purine-substituted acrylates kutentha ndi kupanikizika.Ma acyclic nucleosides okhala ndi gulu la chiral pa malo a 1 ′.Mankhwala a Nucleoside ali ndi zochitika zambiri zamoyo, ndi gulu lofunika kwambiri la mankhwala ndi mankhwala osokoneza bongo, ali ndi udindo wofunikira mu mankhwala odana ndi zotupa, anti-viral ndi anti-AIDS, ndipo panopa amadziwika kuti ndi mankhwala oletsa tizilombo toyambitsa matenda. ..

Hongwu Nano ali ndi nthawi yaitali khola kotungaRhodium nanoparticlenano rhodium ufa ndi zida zina zolemekezeka za nano (Ag, Pt, Ru, Ir, Pd, Au, etc.).

Takulandirani kuti mutiuze kuti mudziwe zambiri.
