| 摘 要： | 以Zr(NO3)4·3H2O为锆源，通过直接合成法得到了Zr-MCM-41介孔材料，考察了不同Zr/Si摩尔比对样品的影响，其中Zr/Si的摩尔比最大为0.25。随着Zr/Si的摩尔比的增加，2θ=2°附近的100晶面的衍射峰强度逐渐降低，当Zr/Si摩尔比大于0.25后得不到介孔Zr-MCM-41材料。对所得样品采用XRD、TG-DTA、N2吸附 脱附几种分析方法进行了表征。

| Abstract: | Zr-MCM-41 mesoporous materials were prepared via a direct-synthesis method using Zr(NO3)4·3H2O as a precursor. The samples were characterized with XRD (X-ray Diffraction), TG-DTA (Thermogravimetry-Differential Thermal Analysis) and N2 adsorption. The effects of Zr/Simolar ratio on the Zr-MCM-41 were then investigated. The results show that the peak of 100 near 2θ=2° in XRD patterns becomes weaker with the increase of Zr/Si molar ratio. To obtain the mesoporous Zr-MCM-41, the maximum of Zr/Si molar ratio is 0.25. The BET area of the Zr-MCM-41samples decreases with the increase of Zr/Si ratio, but the pore size keeps as 2.75nm～2.97nm. |
