METHOD AND CATALYST FOR MAKING CHLORINE DIOXIDE

摘要

Heterogeneous solid catalyst based on platinum group metal oxides are disclosed which are substantially insoluble in aqueous solutions of strong acids. These catalysts are mixed oxide structures comprising mixtures of at least two metal oxides, such as a valve metal oxide with a platinum group metal oxide or a combination of oxides of at least two platinum group metals. Catalytic processes for using such heterogeneous catalysts to produce chlorine dioxide are also shown.
