Abstract

The invention relates to the technical field of catalysts, in particular to a palladium-copper catalyst and a preparation method and application thereof. The preparation method of the palladium-copper catalyst comprises the following steps: preparing palladium nanoparticles: dissolving palladium acetate in absolute ethyl alcohol, and performing treating at the constant temperature of 0-20 DEG C for 24-48 hours to obtain an absolute ethyl alcohol solution containing the palladium nanoparticles; preparing a palladium-modified copper-based metal organic framework: dissolving trimesic acid in the absolute ethyl alcohol solution containing the palladium nanoparticles, adding a copper nitrate aqueous solution, performing uniform mixing, and performing solvothermal reaction to obtain the palladium-modified copper-based metal organic framework; and performing roasting: roasting the palladium-modified copper-based metal organic framework in an inert gas atmosphere to obtain the palladium-copper catalyst taking the porous carbon as the carrier. According to the preparation method, the palladium-copper catalyst with good catalytic activity on furfural can be obtained, and the preparation method is simple in step, does not need to additionally use a reducing agent, and has a better industrial application prospect.

Description

technical field [0001] The present application relates to the technical field of catalysts, in particular to a palladium-copper catalyst and its preparation method and application. Background technique [0002] Catalytic hydrogenation of furfural to prepare furfuryl alcohol is an important chemical production process. At present, the catalysts used for hydrogenation of furfural are mainly supported copper-based catalysts. However, the catalytic activity of ordinary copper-based catalysts is average, so it is necessary to develop new catalysts to improve their ability to catalyze furfural. Not only that, when modifying the existing copper-based catalysts, the preparation method often requires complicated steps or must introduce a reducing agent, which limits the industrial application of copper-based catalysts to a certain extent. Contents of the invention [0003] The purpose of this application is to provide a palladium-copper catalyst and its preparation method and appl...
