Layered double hydroxide precursors, their preparation methods and catalysts prepared therefrom

摘要

Described are novel layered double hydroxide materials useful as intermediates in catalyst formation, and methods of preparing the layered double hydroxides. Further described are catalysts suitable for catalyzing the hydrogenation of CO2 to methanol, and methods for preparing the catalysts. The LDH-derived catalyst according to the invention is active in the hydrogenation of CO2 to methanol and shows improved activity with respect to Cu / ZnO catalysts derived from copper-zinc hydroxycarbonate precursors.
