Abstract: Provided is an exhaust catalyst that exhibits higher NO X -reducing activities at the time of engine restart while maintaining its catalytic activities during normal traveling. This invention provides an exhaust cleaning catalyst 7 comprising a substrate 10 and a catalyst coating layer 30 that includes CeO 2 . Catalyst coating layer 30 is constituted in its thickness direction with multiple coating layers. In a top coating layer 50 located at the outermost surface, the CeO 2 content in a top coating layer's upstream portion 51 is less than the CeO 2 content in a top coating layer's downstream portion 52; and the CeO 2 content in the top coating layer's upstream portion 51 is less than the CeO 2 content in a lower coating layer 40. The CeO 2 content per liter of catalyst volume in the entire coating layer is 10 g/L to 30 g/L.
Abstract translation: 本发明提供一种排气催化剂，其在发动机重新启动时表现出更高的NO X还原活性，同时在正常行驶期间保持其催化活性。 本发明提供了一种排气清洁催化剂7，其包括基材10和包含CeO 2的催化剂涂层30。 催化剂涂层30在其厚度方向上具有多个涂层。 在位于最外表面的顶部涂层50中，顶部涂层上游部分51中的CeO 2含量小于顶部涂层下游部分52中的CeO 2含量; 并且顶部涂层上游部分51中的CeO 2含量小于下部涂层40中的CeO 2含量。在整个涂层中每升催化剂体积的CeO 2含量为10g / L至30g / L.
