Abstract: It is an object of the present invention to provide an anode for a zero-gap brine electrolyzer which through employment of a highly roughened surface at a catalyst layer at an anode for a zero-gap brine electrolyzer makes it possible to achieve sufficient liquid permeability and further reduction in electrolyzing voltage and a brine electrolysis method employing same. The present invention relates to an anode for a zero-gap brine electrolyzer equipped with a liquid-permeable conductive substrate 21, and with a catalyst layer 22 which is provided on the conductive substrate 21 and which is such that the maximum difference in height of surface irregularities is 55 ?m to 70 ?m; a zero-gap brine electrolyzer equipped with the anode 20, a cathode 30, and an ion-exchange membrane I disposed between and in contact with the anode 20 and the cathode 30; and a brine electrolysis method employing same.

Abstract: Provided is a chlorine dioxide-generating product comprising an inorganic porous carrier carrying a chlorite and an alkali agent. In the product, the alkali agent is carried in an amount of more than 0.7 molar equivalent and not more than 2 molar equivalents relative to the amount of the chlorite carried, and the product has a water content of 10% by weight or less. The chlorine dioxide-generating product can stably generate chlorine dioxide gas in an amount that sufficiently achieves deodorization, sterilization, virus removal, mold prevention, antisepsis, or the like of spatial environments, foods, or others but exerts no harmful effect on humans, over a long period of time.
