| description | The invention discloses a preparation method and application of a waste polyester alcoholysis catalyst, and the preparation method comprises the following steps: (1) fully dissolving a certain amount of a boron source, a nitrogen source and a metal source in a proper amount of deionized water, heating to a certain temperature, and fully stirring until the solution is evaporated to obtain a precursor solid; and (2) grinding the precursor solid, and calcining the precursor solid in a tubular furnace to obtain the metal-doped boron nitride. The method has the advantages that the preparation method is simple, the cost is low, the catalyst is stable, the reaction condition is mild, and the defects that a traditional PET alcoholysis catalyst is low in cycle index, poor in catalytic effect and the like are overcome. A new thought is provided for efficient treatment of the PET waste, and the method has a relatively great practical application prospect.
