Abstract 

The mesoporous materials Ag/Co3O4-insitu, Ag/Co3O4-post and pure Co3O4 were prepared by different synthesis methods and then their catalytic activity for formaldehyde oxidation were tested. The catalyst prepared by post-impregnation method (Ag/Co3O4-post) showed the best activity. The characterization reveals that the mesoporous structure of Ag/Co3O4-post was destroyed during the Ag loading process, enhancing its reducibility and exposing more Co3+ and O defects, which then strengthen its catalytic activity.
