1. A method for synthesis of hydrogen peroxide using a composite membrane having a substrate, a hydrogen contact side, and an oxygen contact side, wherein the method comprises:

  • (a) placing hydrogen in contact with the hydrogen contact side of the composite membrane to produce at least one electron and at least one proton;

    (b) placing oxygen in contact with the oxygen contact side of the composite membrane; and

    (c) conducting the at least one electron and the at least one proton produced in step (a) to an interface between the oxygen contact side of the composite membrane and the oxygen such that the at least one electron and the at least one proton react with the oxygen to form a reaction product comprising hydrogen peroxidewherein the substrate operatively connects the hydrogen contact side and the oxygen contact side, the hydrogen contact side comprises an oxidizing catalyst, and the oxygen contact side comprises a reducing catalyst which comprises, in elemental or combinative form, lanthanum, zinc, cerium, praeseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, bismuth, or indium.
