The invention belongs to the technical field of electrochemical analysis, discloses a preparation method and application of an RE-MOF-coated C60/beta-CD/GCE electrode for detecting dichlorophenol in a water body, and particularly relates to an electrochemical sensor based on a rare earth metal organic framework, fullerene and water-soluble beta-cyclodextrin ternary nano composite material, which is used for detecting 2, 4-dichlorophenol in the water body. And 2, 2-methylenebis (4-chlorophenol) is obtained. The electrical conductivity of the composite material is remarkably improved by embedding RE-MOF into C60, then RE-MOF is compounded with beta-CD, and the electro-catalytic oxidation activity of Dcp is remarkably enhanced by utilizing the subject-object recognition effect of RE-MOF and beta-CD. The prepared electrode has low detection limit and good reproducibility, stability and selectivity, is successfully applied to detection of Dcp in an actual water sample, and shows good recovery rate.
