NOVELTY - Catalyst comprises catalyst precursor and graphene oxide. The catalyst precursor is metal solid solution including two metal element, and the metal elements are copper, cerium, nickel, or aluminum. The molar ratio of the two metal elements is 0.2-0.8:0.8-0.2. USE - The catalyst is useful for recycling thermosetting epoxy resin. ADVANTAGE - The catalyst realizes selective catalysis, and reduces inactivation of the inner covered atom. The method uses high value-added chemical e.g. p-isopropylphenol, bisphenol A and 2,2-phenylpropane. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for preparing catalyst comprising (1) adding precipitating agent to metal salt solution, performing co-precipitation, filtration, drying, calcination and grinding to obtain catalyst precursor, and (2) mixing catalyst precursor and graphene oxide in dispersant evenly, filtering, drying, calcining and grinding to obtain catalyst. a method for recycling thermosetting epoxy resin comprising mixing thermosetting epoxy resin, catalyst, hydrogen-rich solvent and acidic solution to carry out catalytic pyrolysis reaction to obtain a pyrolysis reduction product.
