Effect of Additives on the Catalytic Decomposition of Hydrogen Peroxide

摘要

The influence of phosphate, tin, aluminum, sulfate, nitrate, chloride and ammonia on the decomposition of hydrogen peroxide with a silver catalyst have been studied. The first three of these alter the behavior of the peroxide considerably. All three increase the starting activity in a laboratory apparatus, aluminum being the most effective. Phosphate and tin exhibit inhibitory properties during the later phases of the decomposition runs and both increase the rate of silver solution. Phosphate has a greater influence than tin in both of these respects. The extent of starting activity, inhibition and catalyst loss is dependent on the concentration of these substances but they appear to reach their maximum effect at low concentrations. (Author)
