ABSTRACT:
Disclosed is a catalytic material of a calcined noble metal-doped hydrous titanium oxide with a copper promoter compound. The catalytic material is effective for NO.sub.x reduction in an oxidizing exhaust stream form a combustion process is disclosed. Also described is a device for reduction of nitrogen oxides in an exhaust stream, particularly an automotive exhaust stream, that includes a substrate coated with the activated noble-metal doped hydrous metal oxide of the invention and methods for preparing the device.
