Abstract: An electroactivated film that includes: a first electrode that is spaced apart from a second electrode, a water insoluble electrically conductive medium which is permeable to moisture and oxygen and which contacts both electrodes, an electrocatalyst which can be reversibly oxidized and reduced and which facilitates the production of a peroxide when an electrical potential is imposed across the electrodes, and optionally a peroxide-activating catalyst which converts the peroxide to an activated peroxide, wherein one or both electrodes have electrocatalyst immobilized thereupon.

Abstract: Supported catalysts are manufactured from a pretreated porous support material and a nanocatalyst solution of catalyst nanoparticles. The porous support material is pre-treated with a gaseous solvent (e.g., steam or alcohol) to protect the support material from cracking during impregnation of the nanocatalyst solution. The supported catalysts have more uniform size, lower attrition of metals during manufacturing and use, and improved distributions of metal loading compared to catalysts manufactured using known techniques. Hydrogen peroxide manufactured from such catalysts is less likely to be contaminated with catalyst metal.

Abstract: Provided is method and apparatus for regenerating basic hydrogen peroxide (BHP) solution. Such solution is run through filters which are alternated for continuous filtration thereof, while the non-used filter is being cleaned. The filtered BHP solution is then reacted with H.sub.2 O.sub.2 and KO.sub.2 or KOH in a cooled reactor and again filtered and fed to a cooled storage tank as replenished BHP solution. The replenished BHP solution can then be fed to a singlet oxygen generator (SOG) for reaction with Cl.sub.2 to emit singlet delta oxygen (to fuel a COIL laser system) and depleted BHP solution, which is then recycled for filtration and regeneration as before. Thus the process of the invention provides for continuous regeneration of BHP solution for extended use in a COIL. That is, extended COIL run times are required by a COIL for welding and/or cutting operations. At the same time the process of the invention minimizes the amount of BHP required to run the COIL since the BHP is regenerated and recycled.

Abstract: Potassium superoxide can be used to generate and regenerate Basic Hydrogen Peroxide, the primary fuel for Chemical Oxygen-Iodine Lasers. The solid reacts with depleted BHP/H.sub.2 O.sub.2 solution consuming one equivalent of hydrogen peroxide and producing two equivalents of hydroperoxide, reversing the chlorine/BHP reaction that evolves singlet delta oxygen, the energetic species in the COIL system. This same regeneration reaction can be used to generate new BHP solutions by reaction of potassium superoxide with dilute hydrogen peroxide or a protic mineral acid such as hydrochloric acid. These reactions of potassium superoxide provide new and useful methods of generating and regenerating BHP, that significantly decrease COIL system weights and environmental impact.

Abstract: Disclosed is a method of carrying out a mobile atom insertion reaction, such as a hydrogen insertion reaction, for the synthesis of reduced, hydrogenated compounds. Such reactions include the production of ammonia and hydrazine from nitrogen, formic acid and methanol from carbon dioxide, and hydrogen peroxide from oxygen. The insertion reactions are carried out at a bipolar mobile atom transmissive membrane comprising a membrane formed of a mobile atom pump material, as a hydrogen pump material, conductive atom transmissive means on one surface of the membrane and conductive atom transmissive means on the opposite surface of the membrane. The mobile atom, such as hydrogen, diffuses across the membrane, to provide a source of hydrogen on the insertion reaction side of the membrane. The insertion reaction side of the membrane is positively biased with respect to a counterelectrode so that a reactant molecule, such as carbon dioxide, is electrosorbed on that surface of the membrane.
