Abstract

The invention provides a copper oxide supported catalyst and a preparation method thereof. The preparation method of the copper oxide supported catalyst includes placing the cerium oxide nanotube carrier in a solution containing a copper compound and an organic ligand, and performing ultrasonic reaction at 60-80° C., followed by drying and roasting. The copper oxide supported catalyst obtained by the method provided by the present invention can completely convert carbon monoxide into carbon dioxide at a relatively low temperature, so it can be inferred that it has higher catalytic activity.

Description

technical field [0001] The invention relates to a copper oxide supported catalyst, a method for preparing the copper oxide supported catalyst and a copper oxide supported catalyst prepared by the method. Background technique [0002] Metal and its oxide catalysts are a broad category of catalysts, including transition metals, rare earth metals and many other metals and oxides. The metal and its oxide catalysts can be single-component catalysts or multi-component catalysts. In order to obtain higher catalyst activity, metals or corresponding metal oxides are usually supported on the surface of solid supports in the form of active components to make supported metal catalysts. Supported metal catalysts can be widely used in reactions such as hydrogenation, dehydrogenation, oxidation, isomerization, cyclization, hydrogenolysis, and cracking. The active components of supported metal catalysts are generally expensive, and their activity mainly depends on the uniformity of disper...
