Zusammenfassung:	The invention discloses a catalyst used for producing isophorone. The catalyst comprises, by weight, 10-40% of aluminum element, 10-30% of magnesium element and 0.2-10% of rare earth element. The invention also discloses a preparation method of the catalyst. The method comprises the following steps: raw materials are weighed according to a certain formula; pressing and kneading are carried out on an extruder, and extrusion molding is carried out; drying is carried out for 8h under a temperature of 120 DEG C, such that a catalyst precursor is prepared; the catalyst precursor is cut into small segments; and thermostatic roasting is carried out for 4h under a temperature of 500 DEG C. The obtained catalyst has the advantages of high activity, high selectivity, mild reaction conditions, long service life, and the like. With the catalyst and the method, production cost is greatly reduced.
