Ordered mesoporous copper-rare earth metal-aluminum composite oxide catalyst and application thereof

The ordered mesoporous copper-rare earth metal-aluminum composite oxide catalyst disclosed by the invention has a highly ordered mesoporous structure and a relatively high specific surface area, and the copper and rare earth metal oxide and the aluminum oxide carrier are tightly interacted and are highly uniformly dispersed. The highly dispersed Cu active component provides a large amount of ethanol dehydrogenation activity or crotonaldehyde hydrogenation centers, and the highly dispersed rare earth metal oxide and the alumina carrier provide a large amount of acid-base active centers for promoting acetaldehyde aldol condensation, so that efficient conversion from ethanol to higher alcohol is finally realized. And meanwhile, the sintering and growth of the oxides of the Cu and the rare earth metals are limited by mutual doping and strong interaction among the oxides of the Cu, the rare earth metals and the aluminum, so that the catalyst shows excellent stability in 500-hour long-time evaluation. 本发明的有序介孔铜-稀土金
