NOVELTY - Metal organic frameworks-reduced graphene oxide supported palladium nanocatalyst comprises catalyst active component nano-palladium encapsulated into cage formed by carrier with NH2-MIL-101(Cr)-reduced graphene oxide as carrier, where amount of NH2-MIL-101 (Cr)-reduced graphene oxide is 1-5%, and catalyst palladium loading 4-5 wt.%. USE - Metal organic frameworks-reduced graphene oxide supported palladium nanocatalyst used as hydrodechlorination catalyst for halogenated phenol (claimed). ADVANTAGE - The metal organic frameworks-reduced graphene oxide supported palladium nanocatalyst is easy to prepare, has reduced graphene oxide adsorption property and stability, small grain size, good dispersibility and stability, improves catalytic performance, and has high catalytic activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing metal organic frameworks-reduced graphene oxide supported palladium nanocatalyst, which involves: (A) preparing NH2-MIL-101 (Cr)-reduced graphene oxide; (B) dispersing NH2-MIL-101 (Cr)-reduced graphene oxide intodistilled water, adding hydrochloric acid in dropwise manner to adjusting pH value of the solution; (C) adding an appropriate amount of H2PdCl4 to the solution, stirring for 4-6 hours, filtering, fully washing into ethanol; and (D) redispersing solid obtained into water, adding reducing agent in dropwise manner at 0-5 degrees C, stirring for 2 hours and filtering mixture, and drying to obtain final product.
