Examples of catalysts known to be particularly effective in this area include platinum, platinum black, silver, cobalt or reduced palladium (either as gauzes or on supports), and the active manganese ore, pyrolusite. These systems are particularly unique in their high activity in acidic solutions. The major drawback with heterogeneous decomposition catalysts is their propensity to lose activity in the presence of oils, inorganic phosphates, colloidal tin and silica complexes, etc. Similarly, highly acidic liquors or those containing strong chelating agents tend to leach the catalysts from their supports.
