Abstract: The present invention provides a supported metal catalyst with synergistic sites, a preparation method therefor and an application thereof. The preparation method of this catalyst is to utilize the unsaturated cubane-like structure, M cation with catalytic activity is introduced into the cluster core unit. By using the vertex vacancy as the capturing center, and adjusting the impregnation temperature to maximize the loading of the cluster precursor, as well as depending on the electrostatic adsorption of the support and the confinement of the cluster structural unit, the number of S vacancies and the distance between S vacancies and Miso sites are effectively controlled through liquid phase reduction and atmosphere treatment at room temperature to obtain supported X3MSx/Al2O3 catalyst with Miso-Vs synergistic sites. The method of the present invention achieves the joint enhancement of the activity, product selectivity, and stability of unsaturated carbon oxygen bond selective hydrogenation, carbon chlorine bond selective hydrogenation dechlorination, and carbon hydrogen bond dehydrogenation reactions. This catalyst is mainly used in various catalytic reaction processes in the fields of petrochemical, fine chemical, environmental chemical, and other fields. It has outstanding catalytic performance, excellent activity, selectivity, and good recyclability, and is easy to recover and reuse.

Abstract: Catalyst systems are provided for reforming of hydrocarbons, along with methods for using such catalyst systems. The catalyst systems can be deposited or otherwise coated on a surface or structure, such as a monolith, to achieve improved activity and/or structural stability. The metal oxide support layer can correspond to a thermally stable metal oxide support layer, such as a metal oxide support layer that is thermally phase stable at temperatures of 800° C. to 1600° C. The catalyst systems can be beneficial for use in cyclical reaction environments, such as reverse flow reactors or other types of reactors that are operated using flows in opposing directions and different times within a reaction cycle.

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.
