Abstract: The present disclosure relates to a copper-based catalyst for reverse water gas reaction including a gas-permeable amorphous shell formed by strong metal-support interaction. The inventors of the present disclosure synthesized a copper-ceria solid solution and then adjusted the surface defect sites of the solid solution, thereby producing a catalyst including enhanced surface defect sites and having a gas-permeable amorphous shell structure formed on each copper particle. When the catalyst production method according to the present disclosure is used, it is possible to synthesize a catalyst including a structure consisting only of very small Cu particles encapsulated by surface shells and Cu sites incorporated into the CeO2 lattice structure. When the synthesized catalyst is used in the RWGS reaction, it exhibits excellent low-temperature activity, high activity and durability, compared to conventional precious metal catalysts. In addition, even when the catalyst of the present disclosure is supported on a monolith and used to perform the RWGS reaction on a bench scale, it exhibits high activity, CO2 conversion and durability, which are comparable with those in the laboratory scale, indicating that it may be applied to an actual process.

Abstract: A solid heat carrier catalyst for thermal desorption of organic matter-contaminated soil and a method for preparing the same. A hollow alumina ball prepared by 3D printing is taken as a solid heat carrier, copper-nickel-vanadium composite oxide is taken as a catalytic active component, and vinyltriethoxysilane is taken as a masking agent. The ball has a diameter of 30 mm to 60 mm and a thickness of 1 mm to 2 mm. An outer surface of the ball is masked with the vinyltriethoxysilane; then the ball is pierced to make an inner surface thereof connected with the outside through channels; the ball is then immersed in a catalytic active component precursor solution; and finally, drying and calcination are performed to obtain the solid heat carrier catalyst for thermal desorption of organic matter-contaminated soil. This product is widely applicable to the field of thermal desorption of organic contaminants of soil.
