1介孔纳米二氧化锆的微观结构及其应用显示文摘在无任何稳定剂存在的条件下, 用固态反应-结构导向合成出了介孔纳米二氧化锆分子筛. 所得产品拥有层状或MSU结构, 比表面明显高于文献值, 同时, 其介孔纳米特性稳定性高, 在较高温度下仍能维持. 将该样品引入到甲醇合成用Cu基催化剂后赋予催化剂纳米尺度, 从而改变了催化剂的理化结构和电荷性质, 使Cu基催化剂显示较高的催化活性和优良的选择性. 由不同制备方法所得催化剂反应性能的差异, 探讨了甲醇合成催化剂的可能活性位结构.刘欣梅 阎子峰 G.Q.Lu 2004科学通报2004,49,6:20
2介孔材料MCM-41的合成与性能表征显示文摘在水热条件下用新的合成控制手段得到孔壁较厚的MCM 41介孔分子筛材料 ,并采用XRD、N2 吸附、TG DTA、SEM和吡啶程序升温脱附等测试手段对合成的MCM 41样品进行表征 ,结果表明合成的介孔材料结晶度比较高 ,具有六方排列的孔道结构 ,孔径分布较窄 ,BET表面积较大 ,样品热稳定性高 ,吡啶 TPD谱图表明样品具有弱的或中等强度的酸性。用MCM 41作为活性组分制备成催化剂 ,进行微反活性实验 ,表明其裂化活性较低 。宋春敏 阎子峰 王槐平 Max G.Q.Lu 2001燃料化学学报2001,29,z1:5
3Microstructure and application of mesoporous nanosize zirconia显示文摘The mesoporous nanoscale zircoina zeolite was firstly synthesized via solid state —— Structure directing method without addition of any stabilizer. The sample bears lamellar or worm pore structures, relatively high surface area compared with that reported. The mesoporous nanosize structure can also resist higher calcination temperature. The introduction of above zirconia to the catalyst of methanol synthesis dedicates the nanosize particle size to the catalyst, which significantly changes the physical structure and elec-tronic effect of the catalyst. The catalyst shows higher catalytic activity and selectivity to methanol. The active sites for methanol synthesis are demonstrated over various cata-lysts in this paper.LIUXinmei YANZifeng G.Q.Lu 2004Chinese Science Bulletin2004,49,9:2
4Laponite层柱粘土对介孔纳米二氧化锆的稳定作用显示文摘以Laponite层柱粘土作为结构稳定剂,用固态反应结构导向法制备了介孔纳米二氧化锆.考察发现Laponite的引入不仅显著改善了二氧化锆的热稳定性,而且在主体MSU结构中呈现出部分层状结构.从而意味着Laponite在二氧化锆的合成过程中还起到部分硬模板的作用.Laponite的稳定作用主要是通过表面活性剂亲水集团的纽带作用,抑制了二氧化锆的晶化过程和团聚功能,进而抑制粒子的长大实现的.刘欣梅 阎子峰 G.Q.Lu 2005科学通报2005,50,3:1

8Preparation and catalytic properties of ZrO_2-Al_2O_3 composite oxide supported nickel catalysts for methane reforming with carbon dioxide显示文摘ZrO 2-Al 2O 3 composite oxides and supported Ni catalysts were prepared, and characterized by N 2 adsorption /desorption, X-ray diffraction(XRD) an d X-ray photoelectron spectroscopy(XPS) techniques. The catalytic performance and carbon deposition was also investigated. This mesoporous composite oxide is shown to be a promising catalyst support. An increase in the catalytic activity and stability of methane and carbon dioxide reforming reaction was resulted from the zirconia addition, especially at 5wt% ZrO 2 content. The Ni catalyst supported ZrO 2-Al 2O 3 has a strong resistance to sintering and the carbon deposition in a relatively long-term reaction.HAOZheng-ping HUChun JIANGZheng G.Q.LU 2004Journal of Environmental Sciences2004,16,2:0
