Abstract:
To provide an oxygen storage material that is capable of exhibiting an excellent oxygen storage capacity (OSC) even at a low temperature of about 300° C. and has a sufficiently high efficiency of use of cerium contained therein. An oxygen storage material including a ceria-zirconia-copper oxide-based composite oxide that contains cerium, zirconium, and copper, in which at least part of the copper is solid-dissolved in a composite oxide of the cerium and the zirconium, the ceria-zirconia-copper oxide-based composite oxide has a composition expressed by the following chemical formula (1):   Ce x Zr y Cu z O 2-z   (1) where x, y, and z are numbers each satisfying conditions of x=0.3 to 0.7, y=0.15 to 0.7 (exclusive of y=0.7), z=0 to 0.15 (exclusive of z=0), and x+y+z=1, and a specific surface area of the ceria-zirconia-copper oxide-based composite oxide is 2 to 50 m 2 /g.

Claim (Index 7):
The method for producing an oxygen storage material according to  claim 6 , wherein\n the mixture is obtained by mixing cerium nitrate, zirconium nitrate, copper nitrate, and a hydrophilic organic compound in a solvent.
