Iinanoparticles zentsimbi ezihloniphekileyozisetyenziswe ngempumelelo njenge-catalysts kwi-hydrogenation yeepolymers ezinobunzima bemolekyuli ephezulu.Ngokomzekelo, i-rhodium nanoparticle / nanopowders ibonise umsebenzi ophezulu kakhulu kunye nokukhetha okulungileyo kwi-hydrocarbon hydrogenation.

I-olefin ibhondi ephindwe kabini idla ngokuhambelana neqela elikhulu elisebenzayo-iqela le-hydrocarbon, okwenza kube nzima ukuvula i-double bond.Ngokudityaniswa kwe-20nm i-rhodium powder, kulula ukuvula ibhondi ephindwe kabini kwaye wenze ukusabela kwe-hydrogenation kakuhle.

I-Olefins enokuthi i-catalyzed yi-nano rhodium ibandakanya i-1-hexene, i-cyclohexene, i-2-hexene, i-butenone, i-mesityl oxide, i-methyl acrylate, i-methyl methacrylate, kunye ne-cyclooctene, phakathi kwabanye.Ubukhulu bamasuntswana ahlukeneyo bunefuthe kumsebenzi we-catalytic.Ngokuqhelekileyo, ubungakanani besuntswana elincinci, ngokukhawuleza izinga le-hydrogenation.

IYunivesithi yaseHenan Normal kunye neZiko leKhemistry, i-Academy yaseTshayina yeSayensi baye basebenzisana nokuphuhlisa indlela entsha ye-asymmetric catalytic synthesis yeklasi ye-chiral acyclic nucleoside compounds.Ukusebenzisa i-complex eyenziwe yi-nano rhodium (Rh) kunye ne-chiral bisphosphine ligand (R) -BINAP njenge-catalyst, uchungechunge lwamatyathanga asecaleni lulungiswe nge-asymmetric hydrogenation ye-α-purine-substituted acrylates kwiqondo lokushisa kunye noxinzelelo.I-Acyclic nucleosides equkethe iqela le-chiral kwindawo ye-1.Iikhompawundi zeNucleoside zinoluhlu olubanzi lwemisebenzi yebhayoloji, ziludidi olubalulekileyo lwamachiza kunye naphakathi kweziyobisi, zinendawo ebalulekileyo kumachiza alwa nethumba, alwa nentsholongwane kunye ne-AIDS, kwaye okwangoku zibonwa njengawona machiza anokulwa nentsholongwane. ..

I-Hongwu Nano inonikezelo oluzinzileyo lwexesha elideI-Rhodium Nanoparticlei-nano rhodium powder kunye nezinye izinto ezihloniphekileyo zensimbi ze-nano (Ag, Pt, Ru, Ir, Pd, Au, njl.).

Wamkelekile ukuba uqhagamshelane nathi ngolwazi oluthe vetshe.
