Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a starter catalyst purifying an exhaust gas from an Otto engine. SOLUTION: This starter catalyst is composed of palladium and balium oxide on aluminum oxide and is precipitated on the carrier material and aluminum oxide in a state where balium oxide and palladium are jointly dispersed, and the average grain size of the palladium crystallines is 3 to 7 nm.
