    • An automobile exhaust gas purification catalyst comprised of a support mainly comprised of ZrO 2 in which Rh is supported as a catalyst metal preventing sintering of the support, raising the supporting efficiency, and raising the low temperature activity and a method of production of the same are provided. An automobile exhaust gas purification catalyst comprised of a support mainly comprised of ZrO 2 , sintered under firing conditions where the as fired ZrO 2 will substantially not be charged in a catalyst metal supporting treatment solution, in which Rh is supported as a catalyst metal in a particle state. The method of production includes a step of charging the support mainly comprised of ZrO 2 fired under the above firing conditions by applying at least one treatment of an acid treatment and a base treatment and a step of dipping the charged state support in the catalyst supporting treatment solution including a colloid of Rh as the catalyst metal to make the Rh colloid be adsorbed on the support.
    • 一种汽车废气净化催化剂,其主要由作为催化剂金属负载的Zr的ZrO 2的载体组成,防止了载体的烧结,提高了支撑效率,提高了低温活性及其制造方法。 提供。 一种汽车废气净化催化剂,由主要由ZrO 2组成的载体组成,在烧成条件下烧结ZrO 2基本上不会在催化剂金属负载处理溶液中充电,其中Rh作为催化剂金属负载在 粒子状态。 该制造方法包括:在上述烧成条件下,通过进行至少一种酸处理和碱处理的处理以及将带电状态的载体浸渍在催化剂负载处理中的步骤,对主要由在上述烧成条件下烧成的ZrO 2的载体进行充填的工序 包括Rh的胶体作为催化剂金属,使得Rh胶体被吸附在载体上。
