The structure and catalytic properties of porous CeO2 prepared from amorphous alloys by a dealloying method were investigated. The ligament shape of CeO2 could be controlled by using amorphous Ce-Al alloys and crystalline alloys with different atomic arrangements as precursor alloys. The prepared samples showed excellent catalytic properties in soot combustion reactions.
