Beschreibung
Zusammenfassung:	A catalyst support comprises a primary support carrying a coating of acidic and/or amphoteric oxidic material substantially in combination with a basic oxide of group II, III or IV of the Periodic Table. A catalyst having a platinum group metal and/or non-noble metal or oxide on such a support is effective for the treatment of internal combusion engine exhaust gases.
