Abstract

The invention relates to a catalyst containing trace noble metals for dehydrogenating an organic hydrogen storage medium and a preparation method. The catalyst comprises 5-15% of Ni, 0.5-4% of La, 0.01-0.1% of Pt, 0.02-1% of Cu and the balance of carrier active carbon of which the specific surface area is between 100m<2> / g and 1800m<2> / g. The preparation method comprises the following steps of: firstly using processed active carbon as a carrier, using a relevant soluble salt to carry metals, such as the Ni, the La, the Pt, the Cu and the like, then drying and calcining for 3-5h at 300-500 DEGC under the protection of nitrogen gas to prepare the precursor of the catalyst, and finally performing temperature programmed reduction. In the preparation process, by properly proportioning all components and by adopting a combined strategy of alternately using chemical mixing and physical mixing, a multi-component composite catalyst is finally obtained. Therefore, the excellent synergistic catalysis is generated among all components to improve dehydrogenation catalytic activity under the condition that the noble metals are used as few as possible.
