Abstract
An apparatus for the production of hydrogen peroxide is disclosed. In one preferred embodiment, high surface area circulating elements derivatized with a quinone catalyst are reduced in an electrolytic cell where the cathode may also be derivatized with a quinone catalyst and a solution quinone at low concentration is used as a mediator. Once reduced, the circulating elements are separated and used to form hydrogen peroxide from molecular oxygen in an aqueous, electrolyte-free, environment. The circulating elements can be cycled repeatedly. Particular, novel naphthoquinone compounds are also disclosed.
