Catalyst support material having an oxygen storage capacity and a manufacturing method

This patent discloses a method of manufacturing the novel catalyst support having oxygen storage capacity (oxygen storage capacity) of. The catalyst composition ratio is x (Ce1-wZrwO2) :yM:zL: (1-x-y-z) Al2O3, wherein Ce1-wZrwO2 oxygen storage composition having a ratio of ZrO2 0.2-0.8 stabilizer and 5 w 60% by weight ratio of x, M is an agent for promoting the interaction of oxygen storage capacity, with 0-10% by weight y, L is the carrier of Al2O3 stabilizer, 0-10% by weight with z. M or L may simultaneously act as accelerators and heat stabilizers. Ceria - zirconia scope and weight percent other metals and rare earth oxide (x + y + z) with respect to the total oxide is 5-60%. After the platinum group metal (PGM) in combination with the catalyst support, prepared by a new washcoat for use as automobile engine exhaust three-way catalyst converter will require fewer or no requirements Ce-ZrO2 oxide.
