Abstract: The present disclosure discloses a supported polymetallic oxide tandem catalyst, preparation method and application thereof, a surface of the support is supported with an oxide of metal A and then with metal vanadate nano-particles; and the oxide of metal A serves as a direct dehydrogenation catalytic site, and the metal vanadate nano-particles serve as a selective hydrogen combustion site. In the application of the tandem catalyst, dehydrogenation site and selective hydrogen combustion site are coupled at the nano-scale, and this coupling mechanism shifts the reaction equilibrium to the alkenes through the selective combustion of byproduct hydrogen, which effectively surpasses the thermodynamic limit; and meanwhile, the combustion of hydrogen releases chemical energy, and provides heat energy through direct heating, enabling the self-heating operation of the reaction. The present disclosure has the outstanding advantages of high single-pass conversion rate of light alkanes and high selectivity towards target product alkenes.

Abstract: The present disclosure belongs to the technical field of catalyst preparation, and provides a polynorbornene/carbon black-cross-linked three-dimensional network-immobilized bimetallic copper/gold (PNBI/CB-Cu/Au) nanocatalyst, and a preparation method and use thereof. Metallic copper and gold both exist in a form of nanoparticles in the catalyst and are uniformly dispersed, and further enhancing a catalytic performance. Moreover, the carrier is a polynorbornene/carbon black-cross-linked three-dimensional network, and a relative content of free hydroxyl groups in the catalyst is controlled by changing a monomer ratio to adjust a hydrophilic-lipophilic balance value of the catalyst, adapting to a reaction of an organic phase with an aqueous phase. Furthermore, the catalyst is insoluble in conventional solvents, and has a desirable effect in immobilizing nanoscale metallic copper, prolonging a service life of the catalyst.
