Title (EN) METHOD OF MAKING A COPPER OXIDE-TITANIUM DIOXIDE NANOCATALYST
(FR) PROCÉDÉ DE FABRICATION DE NANOCATALYSEUR D'OXYDE DE CUIVRE-DIOXYDE DE TITANE
Abstract:
(EN) A method of making a copper oxide-titanium dioxide nanocatalyst for performing the catalytic oxidation of carbon monoxide is provided. The copper oxide-titanium dioxide nanocatalyst is in the form of copper oxide (CuO) nanoparticles supported on mesoporous titanium dioxide (TiO2) nanotubes. The copper oxide-titanium dioxide nanocatalyst is prepared by adding an aqueous solution of Cu(NO3)2•3H2O to an aqueous suspension of titanium dioxide nanotubes. Deposition precipitation at constant alkaline pH is used to form the copper oxide nanoparticles supported on mesoporous titanium dioxide nanotubes. Aqueous sodium carbonate is used to adjust the pH. The solid matter (copper oxide deposited on titanium dioxide nanotubes) is separated from the suspension, washed, dried and calcined, yielding the copper oxide-titanium dioxide nanocatalyst. Carbon monoxide may then flow over a fixed-bed reactor loaded with the copper oxide-titanium dioxide nanocatalyst at a temperature between 80°C and 200°C.
(FR) L'invention concerne un procédé de fabrication d'un nanocatalyseur d'oxyde de cuivre-dioxyde de titane pour réaliser l'oxydation catalytique de monoxyde de carbone. Le nanocatalyseur d'oxyde de cuivre-dioxyde de titane se présente sous la forme de nanoparticules d'oxyde de cuivre (CuO) supportées sur des nanotubes de dioxyde de titane (TiO2) mésoporeux. Le nanocatalyseur d'oxyde de cuivre-dioxyde de titane est préparé en ajoutant une solution aqueuse de Cu(NO3)2•3H2O à une suspension aqueuse de nanotubes de dioxyde de titane. Une précipitation par dépôt à un pH alcalin constant est utilisée pour former les nanoparticules d'oxyde de cuivre supportées sur des nanotubes de dioxyde de titane mésoporeux. Du carbonate de sodium aqueux est utilisé pour régler le pH. La matière solide (oxyde de cuivre déposé sur des nanotubes de dioxyde de titane) est séparée de la suspension, lavée, séchée et calcinée, fournissant le nanocatalyseur d'oxyde de cuivre-dioxyde de titane. Le monoxyde de carbone peut ensuite s'écouler sur un réacteur à lit fixe chargé avec le nanocatalyseur d'oxyde de cuivre-dioxyde de titane à une température comprise entre 80 °C et 200 °C.
