摘要：
Provided is a carrier for an exhaust gas purification catalyst containing aluminum borate particles having a peak (pore peak) exhibiting the highest intensity in a void volume diameter range of from 20 nm to 100 nm in a logarithmic differential void volume distribution measured using a mercury intrusion porosimeter, in order to provide a new catalyst support capable of effectively suppressing a decrease in catalytic performance caused by sulfur (S) component contained in the exhaust gas, in the case of supporting Pd as a catalytically active component.
