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.
