Abstract

A hydrocarbon and NOx catalyst trap includes a three-way catalyst, and a zeolite layer adjacent to the three-way catalyst and including alumina and silica arranged to form a repeating skeletal frame that defines cavities including active metal active sites for hydrocarbon and NOx trapping such that individual atoms of the active metal are bound to the frame within the cavities via oxygen atoms.
