Title: Method for treating engine exhaust by use of hydrothermally stable, low-temperature NO.sub.x reduction NH3-SCR catalysts

A catalyst composition includes a heterobimetallic zeolite characterized by a chabazite structure loaded with copper ions and at least one trivalent metal ion other than Al.sup.3+. The catalyst composition decreases NO.sub.x emissions in diesel exhaust and is suitable for operation in a catalytic converter.
