▎ 摘　　要

NOVELTY - A catalyst comprises 3 -25 wt. % active components, preferably 5-22 wt. %, 1- 10 wt. % alkaline earth metal component, preferably 1-6 wt. %, 1-10 wt. % rare earth metal and/or transition metal component, preferably 1-8 wt. %, 55- 95 wt. % carrier preferably 64-93 wt. %, where the active component is selected form non-noble metal components, preferably the active component is selected from copper (Cu), iron (Fe), nickel (Ni), cobalt (Co), zinc (Zn), the alkaline-earth metal component is preferably selected from magnesium (Mg), calcium (Ca), and barium (Ba), the rare earth metal and or transition metal component is preferably selected from at least one of lanthanum (La), cerium (Ce), manganese (Mn), and molybdenum (Mo). USE - Catalyst for selective preparation aldehyde or octanol (claimed). ADVANTAGE - The catalyst has good activity and economical efficiency, is suitable for the reaction of octene aldehyde selectivity preparation aldehyde or octene alcohol, under the action of different catalyst, the octylene aldehyde has good conversion rate and selectivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for selectively preparing catalyst which involves configuring the soluble salt corresponding to the active component, the soluble salt corresponding to the alkaline earth metal component, the soluble salt corresponding to the rare earth metal and/or transition metal component and the solution of the component the oxidation graphene after being soaked on the carrier and drying by baking; and (2) a catalyst prepared by the method for selectively preparing a catalyst for selectively preparing aldehyde or octenol.
