Abstract: Chlorine dioxide is generated from an aqueous solution of sodium chlorite in the presence of a catalyst having a reduced rate of deactivation. The catalyst is preferably palladium, or palladium together with another platinum group metal (e.g., Pd+Pt), or palladium together with a Group IB metal (e.g., Pd+Au) deposited on a support modified by Group IA carbonate salt (e.g., K2CO3) or a Group IIA carbonate salt (e.g., CaCO3) or a magnesium salt that can be converted to MgO or a support consisting of a Group IA carbonate salt or a Group IIA carbonate salt or a magnesium salt that can be converted to MgO.
