水热合成bi2wo6/sc光催化剂及其光催化脱硝性能研究
, PP. 735-739
Keywords: 钨酸铋,烟气,光催化,脱硝
Abstract:
？以活性半焦(sc)为载体,采用水热法合成新型可见光催化剂bi2wo6/sc,利用sem、bet、xrd、ft-ir和紫外可见漫反射(uv-vis)光谱等系列手段对所制备的样品进行了表征,并以可见光(λ＞400nm)为光源,模拟烟气中的no为氧化脱除对象,进行光催化活性测试。结果表明,通过水热法合成的bi2wo6具有微米花形状,且光响应波长已扩展到400nm以上的可见光区,bi2wo6/sc光催化脱硝剂性能最好,反应4h后脱硝率仍高于70%。
