Abstract

A találmány tárgyát ipari elektrolizálóberendezésekben oxigénredukálására szolgáló olyan új továbbfejlesztett ródium-szulfidkatalizátor képezi, amely a korrózióval, valamint a szerves vegyületekokozta mérgeződéssel szemben rendkívül ellenálló, ami ezenkatalizátort különösen alkalmassá teszi vizes sósav elektrolízisébenvaló alkalmazásra még olyan esetekben is, amikor szervesszennyezőanyagokat tartalmazó műszaki minőségű sósavat használnak: Azelőállítási eljárás módosításával a katalizátor aktivitása és állagalényegesen javul.
