摘要： The invention provides an electrode comprising a substrate and a coating on the substrate. The coating comprises a plurality of layers, including the following layers in sequence moving outwardly from the substrate: a base layer comprising an oxide of a valve metal; a lower layer comprising an oxide of a platinum group metal and/or an oxide of a precious metal; and a mixed oxide primary layer comprising both: (i) an oxide of a platinum group metal and/or an oxide of a precious metal, and (ii) an oxide of a valve metal and/or an oxide of a group 15 metal. The base layer is devoid of any platinum group metal oxide, and the lower layer is devoid of any valve metal oxide. The present invention also provides methods of manufacturing such electrodes. Also provide are methods of using an electrochemical cell equipped with a certain multilayer coated electrode.

摘要： A point of use electrolysis system can be used to generate oxidizing species within liquid retained by a point of use discharge nozzle, helping to prevent pathogens from growing and multiplying in the nozzle. In one example, a system includes a point of use discharge nozzle having an inlet and an outlet and electrodes. The electrodes are configured to electrochemically generate an oxidizing species within the point of use discharge nozzle. According to the example, the point of use discharge nozzle is configured to trap liquid from a liquid source, when liquid ceases flowing through the point of use discharge nozzle, thereby providing a trapped liquid. Further, the electrodes are configured to generate the oxidizing species within the trapped liquid.

摘要： Dissolved oxygen may be generated by adding a peroxide to a fluid stream and then catalytically decomposing the peroxide to generate oxygen. As the peroxide is catalytically decomposed, the oxygen may solubilize in a surrounding fluid so as to provide dissolved oxygen. In some examples, the amount of peroxide added to the fluid stream is controlled such that substantially all of the hydrogen peroxide added to the fluid stream catalytically decomposes and yet the dissolved oxygen concentration of the fluid stream does not exceed a dissolved oxygen saturation limit for the fluid stream.
