| description | The invention discloses a preparation method of Cu-based catalysts capable of highly efficiently degrading azo dyes, and particularly relates to a method for preparing Cu-based catalysts by virtue of induction of a two-metal-oxide carrier of an oxygen-containing anion insertion layer of an accessory ingredient. Compared with an existing preparation method of Cu-based catalysts in China, the preparation method is characterized in that based on memory-effect self-assembly of a hydrotalcite structure, an original layered structure is restored, the oxygen-containing anion insertion layer of the accessory ingredient enters an interlayer of the two-metal-oxide carrier for inducing the highly scattering of Cu ions, and Cu ions enter a hydrotalcite slab to prepare a ternary layered Cu metal oxide precursor, and then a series of Cu-based catalysts capable of highly efficiently degrading azo dyes is obtained after the Cu component is highly dispersed into the slab. The series of catalysts are high in catalytic activity |
