Abstract: Disclosed are a zirconium-based gold catalyst for a propylene epoxidation reaction and a preparation method therefor. The catalyst uses zirconium-based materials as the support, including ZrO 2 and a zirconium silicon molecular sieve. After obtaining a zirconium-containing precursor by precipitation, ZrO 2  supports of different crystalline phases are obtained by means of changing the calcination temperature. The zirconium silicon molecular sieve is obtained by using Tween as a template and subjecting zirconium n-butoxide and tetraethyl orthosilicate to hydrolysis, crystallization, and calcination. The gold-supporting mode is selected from an equal volume impregnation or deposition-precipitation process. The catalyst is used for the propylene epoxidation reaction, can ensure high selectivity of propylene oxide at low temperatures, and avoids complete oxidation of propylene. After appropriate addition of auxiliaries, the catalyst is desirable to increase the conversion rate of propylene, and at the same time, improves the high temperature selectivity of propylene oxide. Thus, the present invention expands the type of catalyst support used for the reaction, having a broader application prospect.
