Abstract

Carbon monoxide oxidation activity and aging of Cu1−xCrxCo2O4 (0<x<1) spinels in the presence of sulfur oxides have been studied. The results obtained indicate that the sulfur tolerance is related to the presence of octahedral Co3+ (Oh) and Cu2+ (Oh) ions in the ternary spinels.

Abstract

Исследовали активность и старение шпинель Cu1−xCrxCo2O4 (0<x<1) в присутствии окисей серы, являющихся катализаторами окисления закиси углерода. Чувствительность серы приписывают присутствию октаэдрических ионов Co3+ и Co2+ в третичных шпинелях.
