This invention is a composite membrane for chemical synthesis, a chemical reactor into which the composite membrane might be incorporated, and a method of using the composite membrane. The composite membrane comprises a substrate, a first side, and a second side, wherein the substrate operatively connects the first side and second side, the first side comprises an oxidizing catalyst and the second side comprises a reducing catalyst. The reducing catalyst comprises, in elemental or combinative form, lanthanum, zinc, cerium, praeseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, bismuth, or indium. A chemical reactor utilizing this composite membrane can react hydrogen and oxygen to form hydrogen peroxide without direct mixture of the reactants. |
