Title:
PREPARATION METHOD AND APPLICATION OF PT-BASED ALLOY/MOFS CATALYST HAVING HIGH HYDROGENATION SELECTIVITY
Document Type and Number:
WIPO Patent Application WO/2022/213609
Kind Code:
A1
Abstract:
A preparation method and application of a Pt-based alloy/MOFs catalyst having high hydrogenation selectivity. A Pt alloy/MOFs structure in which Pt alloy particles are uniformly loaded on the surface of MOFs is prepared by means of a one-step solvothermal method. The preparation method is simple; the reaction environment is not harsh, and no special atmosphere is needed; the obtained product is unique in structure; metal particles are small in size, uniform in distribution and not prone to loss; moreover, the catalytic activity of metal cannot be affected. In the aspect of catalytic performance, the prepared Pt alloy/MOFs catalyst can be used for catalytic hydrogenation of cinnamic aldehyde at normal temperature and normal pressure, and is excellent in performance. In addition, the catalyst can also catalyze selective hydrogenation of 3-nitrostyrene, and has a wide range of applications.
