Abstract

Catalytic systems containing palladium, copper, and iron compounds on carbon supports—kernel activated carbon and fibrous carbon materials (Karbopon and Busofit)—for the low-temperature oxidation of CO were synthesized. The effects of the nature of the support, the concentration and composition of the active component, and the conditions of preparation on the efficiency of the catalytic system were studied. The catalytic system based on Karbopon exhibited the highest activity: the conversion of carbon monoxide was 90% at room temperature and a reaction mixture (0.03% CO in air) space velocity of 10 000 h−1. It was found that the metals occurred in oxidized states in the course of operation: palladium mainly occurred as Pd+, whereas copper and iron occurred as Cu2+ and Fe3+, respectively.
