Abstract: A catalyst for synthesizing hydrogen peroxide is provided. The catalyst includes first material capable of dissociating hydrogen molecules; and second material capable of suppressing dissociation of oxygen molecules, where one or more interfaces are formed between the first material and the second material. The catalyst can be used as an alternative to the expensive palladium catalysts. In particular, the catalyst can be used for the direct synthesis of hydrogen peroxide.
