Abstract

Ce_1-x O₂:x%Cu²⁺ nanobelts were bioinspired, designed, and fabricated using commercial filter papers as scaffolds by adding Cu(NO₃)₂ in the original sol solution of CeO₂ nanobelts, which display excellent catalyst properties for CO oxidation and photocatalytic activity for organic dyes. Compared with pure CeO₂, CuO belts were synthesized using the same method and the corresponding Ce_0.5O₂:50%Cu²⁺ bulk materials were synthesized without filter paper as scaffolds; the synthesized Ce_1-x O₂:x%Cu²⁺ nanobelts, especially Ce_0.5O₂:50%Cu²⁺ nanobelts, can decrease the reaction temperature of CO to CO₂ at 100 °C with the conversion rate of 100%, much lower than the formerly reported kinds of Ce_1-x O₂:x%Cu²⁺ catalysts. Meanwhile, the synthesized Ce_1-x O₂:x%Cu²⁺ 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 O₂:x%Cu²⁺ nanobelts in catalyst fields.
