Ce 1- x O 2 : x %Cu 2+ nanobelts were bioinspired, designed, and fabricated using commercial filter papers as scaffolds by adding Cu(NO 3 ) 2 in the original sol solution of CeO 2 nanobelts, which display excellent catalyst properties for CO oxidation and photocatalytic activity for organic dyes. Compared with pure CeO 2 , CuO belts were synthesized using the same method and the corresponding Ce 0.5 O 2 :50%Cu 2+ bulk materials were synthesized without filter paper as scaffolds; the synthesized Ce 1- x O 2 : x %Cu 2+ nanobelts, especially Ce 0.5 O 2 :50%Cu 2+ nanobelts, can decrease the reaction temperature of CO to CO 2 at 100 °C with the conversion rate of 100%, much lower than the formerly reported kinds of Ce 1- x O 2 : x %Cu 2+ catalysts. Meanwhile, the synthesized Ce 1- x O 2 : x %Cu 2+ nanobelts also display better photocatalytic activity for organic dyes. All of these results provide useful information for the potential applications of the synthesized Ce 1- x O 2 : x %Cu 2+ nanobelts in catalyst fields.
