Copper-based catalyst, preparation method therefor, and use thereof

Abstract

A method for preparing a copper-based catalyst includes: mixing zinc and aluminum precursors to obtain a first mixed solution, mixing copper and promoter precursors to obtain a second mixed solution, and preparing an alkaline precipitant solution, where the alkaline precipitant solution contains a silica precursor; mixing the first mixed solution with the alkaline precipitant solution, and precipitating zinc and aluminum components to obtain a first suspension; adding the second mixed solution and the alkaline precipitant solution to the first suspension, and precipitating copper component and a promoter to obtain a second suspension; and performing an aging treatment, a drying treatment, and a calcination treatment on the second suspension sequentially to obtain the copper-based catalyst.
