- W903046319 abstract "文章以 HM 沸石-TiO2为复合载体，负载以 WO3或 MoO3为助剂的 V2 O5涂层，制备了WO3（MoO3）-V2O5/CeO2-TiO2/HM作为NOx 的SCR催化剂；采用XRD、N2吸附-脱附和NH3程序升温脱附（N H3-T PD ）对催化剂结构、比表面积和酸性进行了表征；采用常压固定床微型反应器考察催化剂的脱硝性能，着重考察了V2 O5质量分数对脱硝性能的影响。实验结果表明：H M沸石的加入有助于提高 T iO2载体的比表面积，从而有利于V2 O5以单分散态负载；V2 O5负载量为8％的催化剂具有最佳脱硝性能，NO转化率达到93％；当V2 O5负载量大于8％时，V2 O5出现晶体相，催化剂活性反而下降。WO3（M oO3）对V2 O5具有助催化作用，加入后使催化剂上有丰富的酸性位和适度的酸量，有利于催化反应的进行。" @default.
