cas 12135-22-7 mea uamea 75.78% palladium(ii) hydroxide
Folasaga
O fa'amamafa u'amea taua o u'amea mamalu ia e fa'aaogaina lautele i le alamanuia vaila'au ona o lo latou gafatia e fa'avavevave ai le fa'agasologa o vaila'au. O auro, palladium, platinum, rhodium, ma siliva o nisi o faʻataʻitaʻiga o metala taua. O fa'ama'i u'amea taua ia o lo'o aofia ai ni vaega u'amea taua tele e fa'asalalauina i luga o se vaega maualuga e pei o le kaponi, silica, ma le alumina. O nei catalysts e tele fa'aoga i le tele o alamanuia. E iai uiga fa'apitoa ta'itasi u'amea taua. O nei fa'amalosi e fa'aaoga muamua mo fa'agaioiga fa'aola fa'aola. O mea taua e pei o le faʻatupulaia o le manaʻoga mai vaega faʻaaoga mulimuli, popolega i le siosiomaga ma o latou aʻafiaga faaletulafono o loʻo faʻaosoina ai le tuputupu aʻe o maketi.
Meatotino o fa'aupu u'amea taua
1. High gaioioiga ma le filifilia o metala taua i catalysis
O fa'aupuga u'amea taua e aofia ai fa'ata'ape'apeina tele nano-fua u'amea u'amea vaega i luga o lagolago e maualuga i luga e pei o le kaponi, silica, ma alumina. O vaega u'amea fua nano e faigofie ona fa'afefete le hydrogen ma le okesene i le ea. O le hydrogen po'o le okesene e matua malosi lava ona o lona fa'a'ese'ese fa'atasi e ala i le d-electron o fafo mai le atigi o atoma u'amea taua.
2. mautu
O u'amea taua e mautu. Latou te le faigofie ona fausia oxides e oxidation. O oxides o metala taua, i le isi itu, e le mautu. O u'amea taua e le faigofie ona solo i se vaifofo oona po'o alkaline. Ona o le mautu maualuga vevela, ua faaaogaina catalyst uʻamea taua e fai taavale afi faʻamama kasa catalysts.
