Abstract

A találmány tárgya munkaelektródot, ellenelektródot és ionszelektívelektrolitot tartalmazó elektrokémiai reaktorhoz való munkaelektród. Atalálmány lényege, hogy a munkaelektród AxA'(1-x)ByB'(1-y)O(3-d)általános képlettel jellemzett villamosan vezető kerámiaoxid anyagottartalmaz, ahol A és A' hasonló méretű első szubsztitúciós fémeketjelölnek, amely első szubsztitúciós fémek nagy oxigénion-hiányhelycsökkentő hatékonysággal bírnak, és 0<x<1; továbbá B és B' hasonlóméretű második szubsztitúciós fémeket jelölnek, amely másodikszubsztitúciós fémek az első szubsztitúciós fémek méreténél kisebbmérettel rendelkeznek, továbbá nagy oxidációs állapotok közöttiátviteli hatékonysággal bírnak, és 0<x<1; O oxigént jelöl; továbbá d aszubsztitúciós fémek vegyértékeiben jelentkező eltérések kompenzálásátlehetővé tevő kicsiny pozitív vagy negatív szám. A találmány tárgyamég az említett munkaelektródot tartalmazó elektrokémiai reaktor is. Atalálmány emellett nitrogén-oxidok és oxigén elegyében jelen lévőnitrogén-oxidok redukálására szolgáló olyan eljárásokhoz éselektrokémiai reaktorhoz kapcsolódik, amelyeknél az elektrokémiaireaktor munkaelektródot, ellenelektródot, ionszelektív elektrolitot,valamint nitrogén-oxidok elnyelésére szolgáló, elektrokémiairegenerálásra alkalmasan kiképzett nitrogén abszorbert tartalmaz.
