Abstract
The invention is a method and composition for producing carbon dioxide that is based on the reaction or activation of at least one carbon-containing compound with protons. The carbon-containing compound can be in the form of a powder, an impregnated carrier (e.g. zeolite crystals) or an aqueous solution and is preferably selected from the group consisting of carbonates, bicarbonates or sesquicarbonates. The protons are preferably provided by a proton-generating species such as an acid or metal salt. The method and composition can further include a water-retaining substance and/or a chlorine dioxide-producing compound in accordance with the invention.
