A CeWOx catalyst was washcoated on cylindrical cordierite honeycomb for the tests under practical conditions. The catalyst exhibited outstanding NH3-SCR performance. A European steady-state cycle (ESC) test showed that the NH3-SCR system based on the CeWOx catalyst could make the NOx, emission from diesel engine completely meet the Euro V limit without the help of any other after-treatment device.
