Abstract

The invention discloses a porous intermetallic compound and preparation method and application thereof. The pore structure of the porous intermetallic compound includes micropores and mesopores, and the micropores and mesopores are distributed in disorder, wherein the content of the micropores accounts for 6-68%, and the content of mesopores accounts for 32-92%; the specific surface area of the porous intermetallic compound is 50-1600 m²/g, and the porous intermetallic compound is a porous copper silicide intermetallic compound or porous copper-chalcogen intermetallic compound. The invention provides preparation methods of the porous intermetallic compound, and also provides an application of the porous intermetallic compound as a catalyst in the reaction of acetylene hydrochlorination to synthesize vinyl chloride. The porous intermetallic compound catalyst prepared by the invention can carry out the acetylene hydrochlorination reaction in a wide space velocity range, and has good catalytic activity.
