Noble hlau nanoparticlestau ntse siv los ua catalysts hauv hydrogenation ntawm siab molecular hnyav polymers.Piv txwv li, rhodium nanoparticles / nanopowders tau pom muaj kev ua haujlwm siab heev thiab kev xaiv zoo hauv hydrocarbon hydrogenation.

Cov olefin ob daim ntawv cog lus feem ntau nyob ib sab ntawm pawg ua haujlwm loj dua - pawg hydrocarbon, uas ua rau nws nyuaj rau qhib ob daim ntawv cog lus.Nrog rau qhov sib ntxiv ntawm 20nm rhodium hmoov, nws yooj yim qhib ob daim ntawv cog lus thiab ua rau cov tshuaj tiv thaiv hydrogenation smoothly.

Olefins uas tuaj yeem ua kom muaj zog ntawm nano rhodium suav nrog 1-hexene, cyclohexene, 2-hexene, butenone, mesityl oxide, methyl acrylate, methyl methacrylate, thiab cyclooctene, thiab lwm yam.Qhov sib txawv particle loj muaj qhov cuam tshuam rau kev ua haujlwm catalytic.Feem ntau, qhov me me particle loj, qhov ceev ntawm hydrogenation tus nqi.

Henan Normal University thiab lub koom haum ntawm Chemistry, Suav Academy ntawm Sciences tau koom tes los tsim ib txoj kev tshiab rau asymmetric catalytic synthesis ntawm ib chav kawm ntawm chiral acyclic nucleoside tebchaw.Siv lub complex tsim los ntawm nano rhodium (Rh) thiab ib tug chiral bisphosphine ligand (R)-BINAP raws li ib tug catalyst, ib tug series ntawm sab chains tau npaj los ntawm asymmetric hydrogenation ntawm α-purine-hloov acrylates ntawm chav tsev kub thiab siab.Acyclic nucleosides uas muaj chiral pawg ntawm 1′ txoj haujlwm.Nucleoside tebchaw muaj ntau yam kev ua ub no, yog cov chav kawm tseem ceeb ntawm cov tshuaj thiab tshuaj intermediates, tuav ib qho tseem ceeb hauv kev tiv thaiv qog, tshuaj tiv thaiv kab mob thiab tshuaj tiv thaiv AIDS, thiab tam sim no lees paub tias yog cov tshuaj tiv thaiv kab mob tshaj plaws. ..

Hongwu Nano muaj lub sij hawm ntev ruaj khov khoom ntawmRhodium Nanoparticlenano rhodium hmoov thiab lwm yam noble hlau nano cov ntaub ntawv (Ag, Pt, Ru, Ir, Pd, Au, thiab lwm yam).
