Abstract
An exhaust gas purification catalyst composition and a catalyst for exhaust gas purification for automobile, superior in purification performance of a carbon monoxide (CO), a hydrocarbon (HC) and nitrogen oxides (NOx) in exhaust gas discharged from an internal combustion engine of a gasoline vehicle or the like. The exhaust gas purification catalyst composition for purifying a carbon monoxide (CO), a hydrocarbon (HC) and nitrogen oxides (NOx) in automobile exhaust gas, includes a catalyst composition where a rhodium particle (A) is supported on alumina (C) together with a neodymium oxide particle (B), or the like. The neodymium oxide particle (B) having an average particle diameter of 100 nm or smaller, exists at the neighborhood of the rhodium particle (A), as a transfer inhibiting material.
