Nanoparticles metala hanohanoua hoʻohana maikaʻi ʻia ma ke ʻano he catalysts i ka hydrogenation o nā polymers kaumaha molekala kiʻekiʻe.No ka laʻana, ua hōʻike nā rhodium nanoparticle / nanopowders i ka hana kiʻekiʻe loa a me ke koho maikaʻi i ka hydrogenation hydrocarbon.

Hoʻopili pinepine ʻia ka paʻa pālua ʻolefin me kahi pūʻulu hana ʻoi aku ka nui o ka hui hydrocarbon, kahi e paʻakikī ai ka wehe ʻana i ka paʻa pālua.Me ka hoʻohui ʻana o ka pauka rhodium 20nm, maʻalahi ka wehe ʻana i ka paʻa pālua a hana maʻalahi ka hopena hydrogenation.

ʻO nā Olefins hiki ke hoʻopili ʻia e ka nano rhodium me 1-hexene, cyclohexene, 2-hexene, butenone, mesityl oxide, methyl acrylate, methyl methacrylate, a me cyclooctene, a me nā mea ʻē aʻe.Loaʻa i nā ʻāpana ʻokoʻa ka hopena i ka hana catalytic.ʻO ka maʻamau, ʻoi aku ka liʻiliʻi o ka nui o ka nui, ʻoi aku ka wikiwiki o ka hydrogenation rate.

Ua hui pū ʻo Henan Normal University a me ka Institute of Chemistry, Chinese Academy of Science e hoʻomohala i kahi ala hou no ka synthesis catalytic asymmetric o kahi papa o chiral acyclic nucleoside compound.Ke hoʻohana nei i kahi paʻakikī i hana ʻia e ka nano rhodium(Rh) a me kahi chiral bisphosphine ligand (R) -BINAP ma ke ʻano he catalyst, ua hoʻomākaukau ʻia kahi ʻano o nā kaulahao ʻaoʻao e ka hydrogenation asymmetric o nā acrylates i hoʻololi ʻia i ka α-purine i ka lumi wela a me ke kaomi.ʻO nā nucleosides Acyclic i loaʻa kahi hui chiral ma ke kūlana 1'.ʻO nā pūhui Nucleoside he ʻano nui o nā hana olaola, he papa koʻikoʻi o nā lāʻau lapaʻau a me nā intermediates lāʻau lapaʻau, noho i kahi kūlana koʻikoʻi i nā lāʻau anti-tumor, anti-viral a me nā anti-AIDS, a i kēia manawa ua ʻike ʻia ʻo ia nā lāʻau lapaʻau anti-viral loa. ..

Hongwu Nano i lōʻihi-makahiki paʻa lako oRhodium Nanoparticlenano rhodium pauka a me na mea hanohano metala nano (Ag, Pt, Ru, Ir, Pd, Au, etc.).

Welina mai e leka uila iā mākou no ka ʻike hou aku.
