The present application relates to the technical field of catalysts, and relates to a platinum metal catalyst, and a preparation method therefor and an application thereof. The present application provides a platinum metal catalyst; a carrier of the catalyst is mesoporous aluminum oxide; an active component of the catalyst is a platinum metal; the mesoporous aluminum oxide is prepared by means of a sol-gel method; the platinum metal is loaded on a carrier of the mesoporous aluminum oxide in a nano-cluster or monatomic form. The platinum metal catalyst provided by the present application has excellent catalytic activity, selectivity and stability, and has the advantages of high unsaturated alcohol selectivity, high hydrogenation activity, high stability and high metal utilization rate when being applied to a reaction for synthesizing unsaturated alcohol by means of selective hydrogenation of unsaturated aldehyde. |
