    摘要: A catalyst composition is provided that includes a catalytic metal secured to a substrate, and the substrate is mesoporous and has pores that are templated. A catalyst composition includes a catalytic metal secured to a mesoporous substrate. The mesoporous substrate is a reaction product of a reactive solution, a solvent, a modifier, and a templating agent. A method for controlling nitrous oxide emissions including the catalyst composition comprising introducing a regeneration fuel into an exhaust stream upstream relative to the catalyst composition and heating the exhaust stream upstream relative to the catalyst composition. When the regeneration fuel is introduced the air/fuel ratio λ of an air/fuel mixture of a lean burn exhaust is greater than 1.
