Description

technical field

[0001] The invention relates to the technical field of catalyst design, in particular to a phosphoric acid-containing crosslinked polymer-supported palladium nanoparticle catalyst and a preparation method thereof, and the application of the phosphoric acid-containing crosslinked polymer-supported palladium nanoparticle catalyst to catalyze the preparation of hydrogen peroxide. Background technique

[0002] Hydrogen peroxide is an important chemical product, which is widely used in the fields of fine chemical synthesis, food, medicine, and metallurgy, and is an ideal green oxidant. So far, the vast majority of hydrogen peroxide in the industry is produced by the anthraquinone method, but the anthraquinone method is complicated in process, high in energy consumption, easy to explode in the production process, pollutes the environment, and is only suitable for large-scale production. Oxygen exists widely in the air and is cheap. The direct synthesis of hydrogen ...
