Abstract: The present disclosure relates to the technical field of molecular biology, and in particular to a method for preparing a Pt-based alloy/MOFs catalyst with high hydrogenation selectivity, and a preparation method thereof. The present disclosure prepares a Pt-based alloy/MOFs structure with Pt alloy particles uniformly supported on the surface of MOFs in one step through a simple solvothermal method, the preparation method of the present disclosure is simple, the reaction environment is not harsh and does not require a special atmosphere. The resulting product has a unique structure, with small metal particles, uniform distribution and not easy to lose, and it will not affect the catalytic activity of the metal. In terms of catalytic performance, the obtained Pt alloy/MOFs catalyst can catalytically hydrogenate cinnamaldehyde under normal temperature and pressure, and has excellent performance. In addition, the catalyst can also catalyze the selective hydrogenation of 3-nitrostyrene, catalyze the dehydrogenation of tetrahydroquinoline, which proves that the catalyst of the present disclosure has a wide range of applications.
