CAS 12135-22-7 maadada birta 75.78% palladium(ii) hydroxide
Hordhacyo
Kaaliyayaasha birta qaaliga ah waa biraha sharafta leh ee si weyn loogu isticmaalo warshadaha kiimikada iyadoo ay ugu wacan tahay awooddooda ay ku dedejin karaan habka kiimikada. Dahabka, palladium, platinum, rhodium, iyo lacagta ayaa ka mid ah tusaalooyinka biraha qaaliga ah. Kaaliyayaasha birta qaaliga ah waa kuwa ka kooban walxo bir ah oo nano ah oo aad u kala firirsan oo lagu taageeray meel sare sida kaarboon, silica, iyo alumina. Kaaliyayaashani waxay leeyihiin codsiyo dhowr ah oo warshado kala duwan ah. Kaaliyeyaasha birta qaaliga ah kasta waxay leeyihiin astaamo gaar ah. Kaaliyayaashan waxaa ugu horreyn loo isticmaalaa falcelinta isku-darka dabiiciga ah. Arrimaha sida baahida sii kordheysa ee ka timaadda qaybaha isticmaalka dhammaadka, walaacyada deegaanka iyo saameyntooda sharci ayaa kicinaya kobaca suuqa.
Sifooyinka kiciyeyaasha birta qaaliga ah
1. Firfircooni sare iyo xulasho biraha qaaliga ah ee katalisnimada
Kaaliyeyaasha birta qaaliga ah waxay ka kooban yihiin walxo bir ah oo nano-cabbir ah oo aad u kala firirsan oo ku yaal taageerooyin leh meel sare oo dusha sare ah sida kaarboon, silica, iyo alumina. Walxaha birta ee nano-cabbirku si fudud ayay u nuugaan haydarojiin iyo oksijiin jawiga. Haydarojiin ama oksijiinku aad ayuu u firfircoon yahay sababtoo ah nuugistiisa kala go'a iyada oo loo marayo d-electron oo ka soo baxa qolofka atamka birta qaaliga ah.
2.Xasillooni
Biraha qaaliga ah waa kuwo deggan. Si fudud uma sameeyaan oksaydhyo oksaydh ahaan. Oksaydhyada biraha qaaliga ah, dhanka kale, waa kuwo aan xasilloonayn. Biraha qaaliga ah si fudud uma milmaan xalka aashitada ama alkaline. Sababtoo ah xasilloonida kuleylka oo sareysa, kicinta biraha qaaliga ah ayaa loo isticmaalay sidii kicinta nadiifinta gaaska qiiqa baabuurta.
