The invention discloses a supported catalyst and its preparation method and application. The catalyst is composed of a carrier and an active component loaded on the carrier. The carrier is activated carbon, and the active component is composed of palladium, lanthanum, cerium and Composition of boron, the mass of palladium, lanthanum, cerium and boron is respectively 3.0-15.0%, 0.1-5.0%, 0.1-5.0% and 0.1-2.5% of the carrier mass. The invention provides the application of the supported catalyst in the reaction of chlorobenzene compounds represented by formula (I) and alcohol represented by formula (II) to generate phenyl ether compounds represented by formula (III). The catalyst prepared by the invention has good catalytic performance for chlorobenzene compounds, the catalytic conversion conversion rate can reach 100%, the selectivity is over 99%, and the catalyst is stable, not only can realize the effective degradation of chlorobenzene compounds; More valuable phenyl ether organic compounds can be obtained. |
