▎ 摘　　要

NOVELTY - The cathode (101) has advanced oxidation reactor (100) comprises transition-metal foam. The carbon coated on the transition metal foam. The cathode further comprises anode configured and positioned with respect to the cathode such that potential difference is applied across the anode and cathode. The carbon coating comprises three-dimensional graphene. The anode comprises titanium coated with platinum. The reactor vessel comprises gas inlets, includes first gas inlet fluidically connected to ozone generator. The oxygen source is connected to second inlet. USE - Cathode for advanced oxidation reactor (claimed) for producing hydrogen peroxide for reaction with ozone to produce hydroxyl radicals in electroperoxone process. ADVANTAGE - The cathode: is capable of producing hydroxyl radicals and other powerful oxidants capable of breaking almost any organic bond; and utilizes the carbon-coated nickel foam, which has high surface area, high surface tension, and high thermal conductivity, and thus provides the cathode with improved performance and durability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for producing hydrogen peroxide for reaction with ozone to produce hydroxyl radicals in electroperoxone process; and (2) a electroperoxone method for producing hydrogen peroxide for reaction with ozone to produce hydroxyl radicals in electroperoxone process. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of advanced oxidation reactor for producing hydrogen peroxide for reaction with ozone to produce hydroxyl radicals.
