中文摘要：

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〉400 nm）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400 nm以上的可见光区,Bi2WO6/SC光催化脱硝剂性能最好,反应4 h后脱硝率仍高于70%。

英文摘要：

A novel Bi2WO6/ SC photo-catalyst was synthesized by hydrothermal method with semi-coke（ SC）as the support. The as-prepared catalyst was characterized by SEM,BET,XRD,FT-IR and UV-vis diffuse reflectance spectra; its photo-catalytic activity in NO oxidation under visible light irradiation（ λ 〉400 nm） was evaluated. The results indicate that Bi2WO6 obtained by hydrothermal method displays micro-flower structure and absorption spectrum toward the visible light region above 400 nm. The Bi2WO6/ SC catalyst exhibits excellent photo-catalytic activity in NO removal; NO conversion remains higher than 70% after reaction under irradiation for 4 h.
