前驱体溶液ph值对v2o5-wo3/tio2催化剂的低温nh3-scr性能的影响
, PP. 1455-1463
Keywords: 前驱体溶液,v2o5-wo3/tio2,ph值,低温nh3-scr,钒物种,脱硝活性
Abstract:
？采用调节前驱体溶液ph值的方法制备了用于低温nh3-scr的v2o5-wo3/tio2催化剂。通过xps、raman光谱、h2-tpr、nh3-tpd、nh3-drift、xrd及物理吸附等手段对催化剂进行了表征分析,并对其脱硝催化活性进行了测试。结果表明,前驱体溶液酸性的增强能够提高催化剂表面聚合态钒物种和v4+(3+)/v5+的比值以及表面酸性,增加活性位数量、降低反应的活化能、提高其脱硝催化性能。因此,通过提高前驱体溶液的酸性,有助于制备出脱硝活性较好的nh3-scr催化剂。
