cas 12135-22-7 ka kooban bir 75.78% palladium(ii) hydroxide
Hordhacyo
Kiciyayaasha birta qaaliga ah waa biro sharaf leh oo si weyn loogu isticmaalo warshadaha kiimikada taas oo ay ugu wacan tahay awooda ay u leeyihiin in ay dedejiyaan habka kiimikada.Dahab, palladium, platinum, rhodium, iyo qalin ayaa ah qaar ka mid ah tusaalooyinka biraha qaaliga ah.Biraha qaaliga ah waa kuwa ka kooban qaybo bir ah oo aad u kala firdhiyey oo nano ah oo lagu taageerayo meel sare oo sare sida kaarboon, silica, iyo alumina.Kiciyayaashani waxay leeyihiin codsiyo dhowr ah oo ku saabsan warshado kala duwan.Kataliye kasta oo biraha qaaliga ah wuxuu leeyahay astaamo u gaar ah.Kiciyayaashan ayaa ugu horrayn loo isticmaalaa falcelinta synthesis organic.Qodobbada ay ka midka yihiin baahida sii kordheysa ee qaybaha isticmaalka dhamaadka, welwelka deegaanka iyo saameyntooda sharci ayaa horseedaya kobaca suuqa.
Guryaha biraha birta ah ee qaaliga ah
1. Dhaqdhaqaaq sare iyo xulashada biraha qaaliga ah ee catalysis
Waxyaalaha birta ah ee qaaliga ah waxay ka kooban yihiin qaybo bir qaali ah oo miisaan leh oo nano ah oo ku yaal taageerooyinka leh meel sare oo sare sida kaarboon, silica, alumina.Qaybaha birta ee miisaanka nano ayaa si fudud u xajiya hydrogen iyo ogsijiinta jawiga.Haydaroojiinka ama ogsijiinta ayaa aad u fir fircoon iyadoo ay ugu wacan tahay kala qaybsanaanteeda iyada oo loo marayo d-electron oo ka baxsan qolofka atamka birta ah ee qaaliga ah.
2.Xasilooni
Biraha qaaliga ah ayaa xasiloon.Si fudud uguma sameeyaan oksaydhyo oksaydhyo.Okssaydhyada biraha qaaliga ah, dhanka kale, ma xasilaan.Biraha qaaliga ahi si sahal ah uguma milmaan aashitada ama xalalka alkaline.Sababtoo ah xasilloonida kulaylka sare, kicinta birta qaaliga ah ayaa loo isticmaalay sidii kicinta gaasta nadiifinta qiiqa baabuurta.
