Kev Siv
Palladium (II) oxide monohydrate yog ib qho tseem ceeb rau kev npaj ntau yam catalysts uas siv palladium. Yeej, nws siv qhov zoo ntawm cov khoom uas "Pd²⁺ yooj yim txo kom ua Pd⁰ (metallic palladium) uas muaj zog heev", thiab los ntawm kev txo cov tshuaj tiv thaiv, palladium raug thauj mus rau ntawm tus cab kuj los tsim cov catalysts ua haujlwm tau zoo heev.
Siv cov khoom ntawm PdO·H₂O uas cuam tshuam nrog dej ammonia los tsim cov tshuaj tetraamminepalladium(II) uas yaj tau (Pd(NH₃)₄²⁺), cov tshuaj no ua haujlwm ua cov khoom siv plating tseem ceeb hauv cov txheej txheem "ammonia-based palladium plating".
Hauv hydrometallurgy lossis kev siv cov khoom siv pov tseg hlau muaj nqis (xws li cov catalysts siv thiab cov khoom siv hluav taws xob siv), "amphoteric" thiab "kev sib koom tes muaj peev xwm" ntawm palladium (II) monohydrate yog qhov tseem ceeb rau kev sib cais palladium ntawm lwm cov hlau (xws li platinum, rhodium, tooj liab, thiab nickel)
Cov khoom ntawm PdO2 · H₂O thermal decomposition los tsim PdO2 lossis hlau Pd tuaj yeem siv los npaj cov ntaub ntawv ua haujlwm hauv thaj chaw ntawm cov khoom siv hluav taws xob
Hauv kev tshuaj xyuas tshuaj, palladium (II) oxide monohydrate tuaj yeem siv ua cov khoom siv raw rau palladium cov qauv lossis ncaj qha rau kev kuaj pom cov palladium ions.
Ntim thiab Xa Khoom
Lub hnab ntawv ci txhuas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
