Abstract
Disclosed is a method for preparing a copper-zinc-based catalyst used in synthesis of methanol through COhydrogenation, and ultrasonic waves are used for control over crystalline phase's composition of a catalyst precursor. Further related to is a catalyst prepared by such a method. An amount of aurichalcite in an active catalyst precursor can be improved through the method, and the specific surface area of the metal copper in a reduced state catalyst is high. The catalyst presents high activity and hydrothermal stability, and promotes high space time yield of methanol in the synthesis of methanol through COhydrogenation.
