摘要
分别采用沉淀加浸渍法和溶胶凝胶加浸渍法制备了Ag+CuO／ZrO2催化剂。对催化剂进行了比表面积和孔径分布、XRD、H2-TPR等表征,研究了催化剂的反应活性。结果表明:利用沉淀加浸渍制备的样品对NO选择性还原具有较高的反应活性。
A series of Ag^＋CuO/ZrO2 catalysis were prepared by two different methods： copreeipitation - impregnation （cp - im） and sol - gel - impregnation （gel - im ） . The surface area and pore diameter of all the samples were measured , and they were characterized by XRD and tt2 - TPR. their catalysis properties for the selective reduction of NO under lean - burn conditions were investigated. In comparison , the sample was prepared by ep - im, which showed higher NO conversion than the sample prepared by gel- im.
