Surface| Summary: | The effect has been studied of carrier nature (SiO2, Al2O3, ZSM-5 and Erionite) and conditions of surface formation of Co-containing systems on their catalytic activity in CO oxidation. Derivatographic data on formation conditions of Co-carrier system active sites testify different character and interaction grade of cobalt compounds with these carriers. The catalytic activity of these systems is caused by definite content and metal ion ratio in different coordination states (Co2+Td, Co2+Oh and Co3+Oh) and depends on the reducibility of surface Co compounds. |
