1. A method of producing hydrogen peroxide, comprising:
producing a palladium-containing composition that comprises palladium particles and a coating agent that coats a surface of the palladium particles; and
reacting hydrogen with oxygen in a presence of the palladium-containing composition such that hydrogen peroxide is obtained,
wherein the coating agent comprises at least one compound selected from the group consisting of trans,trans-1,5-diphenyl-1,4-pentadien-3-one, and diphenyl sulfone.
