Abstract

original image

The catalyst support 3DOM LaFeO3 contains highly ordered macropores that are connected with each other by small windows. 3DOM LaFeO3 supported gold catalysts, which combine the advantages of good contact by the macroporous support and highly active sites for activation of O2 by gold clusters, exhibit super catalytic performance for soot oxidation.
