The invention relates to a catalyst for VAM (vinyl acetate monomer) synthesis with an acetylene method and a preparation method of the catalyst, and mainly solves the problem that the content of a by-product benzene is high in the prior art. According to a technical scheme adopted by the invention, the VAM catalyst is prepared by adopting activated carbon as a carrier, active components include zinc acetate and a cocatalyst, and the cocatalyst includes at least one metal element selected from VB elements, so that the problem is well solved, and the application to industrial production of VAM synthesis with the acetylene method can be realized.
