An electrolysis method, electrolysis apparatus and layered electrode for chloride-containing water

Abstract

This invention relates to a method, apparatus, and layered electrode for electrolyzing chloride-containing water. The method comprises the following steps: contacting chloride-containing water with a chloride-selective barrier material to obtain treated water; then contacting the treated water with an electrode to induce a water decomposition reaction to produce oxygen and hydrogen, while simultaneously obtaining undecomposed water. The chloride-selective barrier material is selected to satisfy at least one condition explicitly defined in the specification. This invention improves reaction efficiency by employing a selective chloride-selective barrier material, inhibiting chloride ion adsorption. The method is simple and easier to scale up, giving it significant production advantages.
