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.
