Abstract
The CeO2-ZrO2-WO3 (CZW) catalysts are prepared by different methods for the selective catalytic reduction of NO by NH3. The CZW (HT) catalyst (synthesized by hydrothermal method) shows the best catalytic activity and above 90% NO conversion is obtained at 195-450 °C. Furthermore, the CZW (HT) also exhibits the excellent performance in the presence of H2O and SO2. Besides, the hydrothermal method contributes to the formation of Brønsted acid sites and then results in the exceptional high-temperature activity.
