Title (EN) LAYERED DOUBLE HYDROXIDE PRECURSOR, THEIR PREPARATION PROCESS AND CATALYSTS PREPARED THEREFROM
(FR) PRÉCURSEUR D'HYDROXYDE DOUBLE EN COUCHES, SON PROCÉDÉ DE PRÉPARATION ET CATALYSEURS PRÉPARÉS À PARTIR DE CELUI-CI
Abstract:
(EN) New layered double hydroxide materials useful as intermediates in the formation of catalysts are described, as well as methods of preparing the layered double hydroxides. Also described are catalysts suitable for catalysing the hydrogenation of CO2 to methanol, as well as methods for preparing the catalysts. The LDH-derived catalysts of the invention are active in the hydrogenation of CO2 to methanol, and show improved activity with respect to Cu/ZnO catalysts derived from copper-zinc hydroxycarbonate precursors.
(FR) L'invention concerne de nouveaux matériaux d'hydroxyde double en couches utiles en tant qu'intermédiaires dans la formation de catalyseurs, ainsi que des procédés de préparation des hydroxydes doubles en couches. L'invention concerne également des catalyseurs appropriés pour catalyser l'hydrogénation du CO2 en méthanol, ainsi que des procédés de préparation des catalyseurs. Les catalyseurs dérivés de LDH de l'invention sont actifs dans l'hydrogénation du CO2 en méthanol, et présentent une activité améliorée par rapport à des catalyseurs à base de Cu/ZnO dérivés de précurseurs hydroxycarbonate de cuivre-zinc.
