THE Cu-Co-Fe SYSTEM IN CO OXIDATION REACTION IN THE PRESENCE OF HYDROGEN

摘要

The Cu-Co-Fe oxide system is studied in the CO oxidation reaction in the presence of hydrogen. It is shown that the presence of hydrogen in the reaction mixture contributes to the transformation of the Cu_(OH)_3NO_3 phase into the superfine CuO phase, which is more active in CO oxidation in the presence of hydrogen, compared with pure CuO. It is determined that the oxidation of H_2 begins only after almost complete CO conversion into CO_2 for the samples containing the Cu_2(OH)_3NO_3 phase.
