Herein disclosed are compositions for passive NOx adsorption and oxidation that include at least a manganese-based oxide and one or more promoter materials and methods for making and using said compositions. The promotor materials may include a rare earth, transition, or main group metal. The compositions may be used in NOx emission control system and adsorbs NOx compounds at low temperatures and then release NOx at higher temperatures, where the NOx can be oxidized, without the hybridized MnOX composition breaking down. The compositions are capable of maintaining a sufficiently large surface area at high temperatures found in the emissions gas streams of internal combustion engines necessary for the complete elimination of NOx.

Mixed valent manganese-based NOx adsorber

The invention is directed to a method for providing a corrosion inhibiting aqueous solution which includes zinc orthophosphate where the zinc orthophosphate is solubilized. The invention is directed to a method of making a substantially contaminant-free, concentrated aqueous solution of zinc orthophosphate from zinc metal or zinc oxide and aqueous phosphoric acid.

Method for providing a corrosion inhibiting solution

This invention relates to a manganese oxide catalyst composition consisting essentially of at least about 40 weight percent manganese, from about 1 to about 25 weight percent lanthanum, from about 5 to about 20 weight percent copper and from about 20 to about 30 weight percent oxygen, a high temperature stable manganese catalyst/carrier combustion oxidation catalyst composition and a method of destroying VOCs and other gaseous organics using the composition of the invention.
