Abstract: In a fuel cell which has an activated carbon-containing anode and an activated carboncontaining cathode and is preferably used for the oxidative treatment of waste waters containing oxygen or oxygen-containing compounds, the cathode has been subjected to partial anodic oxidation in a mineral acid at a potential .epsilon.h of from +1.3 to +10V and then doped with molybdenum(VI) and/or tungsten(VI) and/or vanadium(V) compounds, and the anode has been subjected to partial anodic oxidation in an aqueous mineral acid, cathodically reduced in an aqueous mineral acid and then impregnated with cobalt hydroxide and/or nickel hydroxide and/or copper hydroxide and/or zinc hydroxide, the anode and the cathode being separated by a porous polyelectrolyte through which the waste water flows.

Abstract: Oxidizable organic and/or inorganic compounds in waters are subjected to catalytic degradation using a catalyst applied to an oxygen-storing inert carrier, for example of graphite, coke, a non-gas-sing coal or active carbon. The carrier used is coated with a cationic dye complexed with heteropolyacids and/ or polyacids and/or salts or metal acids of subgroups V to VIII. The advantages of the process include the prevention of biological growth on the catalyst surface by the biocidal dye cation and the avoidance of calcium and magnesium deposits on the catalyst surface through the presence of the cationic solid.

Abstract: Wastewaters are subjected to an oxidative treatment with a carbon containing catalyst and an oxidizing agent by a process in which the carbon carrier used, eg. graphite, coke or active carbon, is subjected to anodic oxidation in an aqueous mineral acid and then doped with molybdenum(VI) and/or tungsten(VI) and/or vanadium(V) compounds.

Abstract: O.Z. 32,171 An improved process for the manufacture of silver catalysts, in which the silver is applied to conventional dimensionally stable and chemically inert carriers, eg. alumina or quartz moldings, preferably by electroless deposition from silver salt solutions onto a great variety of surfaces acting as carriers, by the use of suitable reducing agents. In a particular embodiment, a uniform deposition of silver and a dense and welladhering silver layer on the surface of the carrier are achieved by adding certain materials to the silver salt solutions.
