以Cr浸渍WO 3-ZrO 2(WZr)制备了一种新型的Cr/WO 3-ZrO 2催化剂,用于NH3选择性催化还原NOx。Cr的引入显著提高了WZr催化剂的NOx还原活性,Cr的最佳负载量为2wt%。Cr/WZr催化剂的氧化还原循环(Cr 3 ++3W6 + ParticipCr 6 ++3W5+)和表面酸性的显著增强是其高NOx还原活性的主要原因。本研究表明,Cr与WO 3-ZrO 2固体酸催化剂的组合具有很好的控制NOx气体排放的前景。
A novel Cr/WO3-ZrO2catalyst prepared by impregnating WO3-ZrO2(WZr) with Cr has been developed for the selective catalytic reduction of NOxwith NH3. The introduction of Cr significantly enhanced the activity of WZr catalyst for the NOxreduction and an optimal loading of Cr is 2 wt%. The redox cycle (Cr3++ 3W6+↔ Cr6++ 3W5+) and the remarkably enhanced surface acidity can account for the high activity of Cr/WZr catalyst for the reduction of NOx. The present study demonstrated that the combination of Cr with WO3-ZrO2solid acid catalyst is promising for the control of NOxgas emissions.
