摘要:
本文以EO20PO70EO20(P123)、正硅酸四乙酯、盐酸和水为原料,合成KIT-6,并以KIT-6作为硬模板制备介孔CuO-CeO2-MOy(M:Zr,Al)催化剂。借助X线衍射(XRD)、N2吸附-脱附(BET)、拉曼光谱和H2程序升温还原(H2-TPR)等手段对催化剂进行表征,并考察催化剂在HCl氧化反应中的催化性能。结果表明:CuO-CeO2-MOy获得了高比表面积(>140 m2/g)和较小的晶粒粒径,CuO物种高度分散在催化剂的表面或者进入CeO2晶格中。CuO-CeO2-ZrO2催化剂获得了最高的表面氧空位浓度和最佳的低温氧化-还原性能,在HCl氧化反应中表现出了最佳的催化活性和热稳定性。
Abstract:
CuO-CeO2-MOy(M:Zr,Al)catalysts were prepared by hard template KIT-6 synthesized from EO20PO70EO20(P123), tetraethyl orthosilicate, hydrochloric acid and water. Relevant characterization was conducted by X-ray diffraction(XRD), N2 adsorption-desorption, Raman spectrum(Raman)and H2 temperature programmed reduction(H2-TPR).The activities of the catalysts for HCl oxidation were investigated. Results showed that CuO-CeO2-MOy(M:Zr,Al)catalysts had a high surface area(>140 m2/g)and small grain sizes, and CuO species could highly disperse on the surface of the catalysts or dissolve into the catalysts. CuO-CeO2-ZrO2 had the most abundant surface oxygen vacancies and the best reducibility at low temperatures, and showed an excellent catalytic activity and good thermal stability in HCl oxidation.
