A kind of graphene-wrapped metal nickel catalyst, preparation method and application thereof |
| abstract |
The invention relates to the field of catalysts, in particular to a graphene-wrapped metal nickel catalyst, a preparation method and applications thereof. A method for preparing a graphene-wrapped metal nickel catalyst provided by the present invention includes the following steps: Step 1: mixing a nickel salt aqueous solution with a carboxyl polydentate ligand, and obtaining a layered complex precursor through a complexation reaction and drying; Step 2: preparing the layered complex precursor by a pyrolysis method to obtain a graphene-wrapped metal nickel catalyst with a core-shell structure. The invention also provides the graphene-wrapped metal nickel catalyst prepared by the above method and the application of the catalyst as catalytic hydrogenation of nitrobenzene. The invention provides a graphene-wrapped metal nickel catalyst, a preparation method and an application thereof, and solves the problems of low catalytic hydrogenation selectivity, poor thermal stability, and inability to recycle and reuse the nickel metal catalyst in the prior art due to dechlorination side reactions. technical problem. |
