Abstract
(EN)
The present disclosure provides for a catalyst comprising at least one group 10 metal impregnated in a mixed metal oxide selected from the group consisting of the oxides of In, Cu. Zn, Zr, Al, and combinations thereof. The catalyst of the present disclosure is effective in conversion of CO2 to value added products like methanol (CH3OH) and carbon monoxide (CO). The present disclosure further discloses a convenient process for preparation of the catalyst.

La présente invention concerne un catalyseur comprenant au moins un métal du groupe 10 imprégné dans un oxyde métallique mixte choisi dans le groupe constitué par les oxydes d'in, Cu, Zn, Zr, Al, et des combinaisons de ceux-ci. Le catalyseur de la présente invention est efficace pour la conversion de CO2 en produits ajoutés de valeur comme le méthanol (CH3OH) et le monoxyde de carbone (CO). La présente invention concerne en outre un processus pratique de préparation du catalyseur.
