The invention relates to a preparation method and application of a microporous material-supported copper catalyst. First, in an agate mortar, DY-32 zeolite, sodium hydroxide, a template agent, water and crystal seeds are uniformly mixed in an oven for crystallization, and the product is washed Na-type SSZ-39 zeolite is obtained by calcining, and H-SSZ-39 zeolite is obtained through ion exchange; the H-SSZ-39 zeolite is subjected to incipient wetness impregnation with a copper salt solution, dried in the shade, vacuum-dried, and then calcined to obtain micropores The material-supported copper catalyst Cu/H-SSZ-39, the above-mentioned microporous material-supported copper catalyst can be used in the catalytic decarboxylation coupling reaction. The catalyst of the invention has high activity, easy separation, good stability, high activity, long service life, less metal residue, simple operation, and simple equipment requirements; and the catalyst of the invention has high activity for repeated recycling, and has the advantages of economy, high efficiency, green environmental protection, etc. advantage. |
