TiO2 NTS-SUPPORTED COPPER OXIDE WITH IMPROVED CATALYTIC PERFORMANCE FOR LOW-TEMPERATURE CO OXIDATION VIA CERIUM OXIDE MODIFICATION

High catalytic activity for CO oxidation can be obtained on TiO2 nanotubes (NTs) -supported copper oxide (CuO/TiO2 NTs). But the relatively low thermal stability limits its practical application. Via cerium oxide modification, catalysts with enhanced catalytic activity and higher thermal stability c...
