Zusammenfassung:	The invention relates to a Pd @MIL-101 composite and a preparation method and application thereof. According to the adopted technical scheme, palladium chloride is added to methyl alcohol while sodium chloride is added, ultrasonic dispersion is conducted, stirring is conducted for 10-20 hours, and sodium tetrachloropalladate is obtained; a sodium tetrachloropalladate solution is dropwise added into MIL-101 crystals slowly, pd@MIL-101 is obtained; a methanol solution of asaturated sodium borohydride is added to the pd@MIL-101, reduction is conducted under the condition of ice-water bath, and the Pd @MIL-101 composite is obtained. The synthesized Pd @MIL-101 composite has special selectivity catalytic activity for phenylboronic acid and 1,4-dibromo-benzene in a suzuki reaction, and the yield of an intermediate product 4-bromobiphenyl is effectively raised.
