NaY分子筛合成体系中添加铝的络合剂（乙二胺四乙酸、柠檬酸和醋酸），可有效地减小分子筛的晶粒尺寸及增加分子筛的晶化速度和SiO2Al2O3物质的量比。在添加柠檬酸的合成体系中，考察了柠檬酸的添加量对NaY分子筛晶化行为的影响。发现存在着一个最佳的柠檬酸的添加量范围，即n（柠檬酸）:n（氧化铝）≤2:1，在此范围内，NaY的晶化速率和硅铝比较高，而晶粒尺寸较小。

导向剂的陈化时间和反应胶的晶化温度可以影响NaY分子筛的晶化行为。随导向剂陈化时间的增加，NaY分子筛的晶化速度加快，晶粒尺寸减小；随晶化温度的升高，NaY分子筛的晶化速度加快，但晶粒尺寸增加.而向合成体系中添加轻稀土离子（Ln3+）对NaY分子筛的晶化行为影响更为明显。与未添加稀土离子时相比较，在一定的稀土离子添加量范围内[n（Ln3+）ön（Al3+）<012]，NaY分子筛的晶化速度明显加快而晶粒尺寸显著减小，同时所合成出的NaY分子筛的n（SiO2）ön（Al2O3）比也有较大的提高。添加稀土离子使合成体系中形成异晶晶种的Ln（OH）3微晶，从而进一步引发NaY分子筛的成核。

A mesostructured V-Mg-O was synthesized for catalytic purposes using vanadium(V) oxide and magnesium chloride as sources and various surfactants or surfactant mixtures as templates. Among the surfactants employed, it was found that cetyltrimethylammonium bromide (CTAB) and the mixture of CTAB and hexadecylamine (HDA) templated fibrous lamellar-like mesostructures. The mixture of CTAB+HDA was more efficient in templating the fibrous mesoporous V-Mg-O than the individual surfactants.

Mesostructured vanadium-magnesium oxides (V-Mg-O) with various morphologies weresynthesized at room temperature using MgCl2 and V2O5 as source materials and a large number of surfactants as templates. It was found that, among the surfactants employed, the quaternary ammonium surfactants with long alkyl chains, such as cetyltrimethylammonium bromide (CTAB), or the nonionic surfactant Triton-X 100 could template V-Mg-O mesostructures. In the former case, the synthesized specimen had a lamellar structure and nanofibrous morphology. In the latter case, the specimen had a lamellar structure but a particulate morphology. Among the binary mixtures of cationic, anionic, or nonionic surfactants employed, only the combinations between a quaternary ammonium surfactant and hexadecylamine (HDA) were effective in templating a lamellar mesophase with nanofibrous morphology. The binary surfactants were more effective than the single surfactants in generating a higher regularity of the lamellar mesostructure. Mesostructured V-Mg-O could be synthesized even using binary mixtures consisting of HDA and a quaternary ammonium surfactant with a short alkyl chain, such as benzyltrimethyl (neither of the two was effective when used alone). The mesostructured V-Mg-O nanofibers synthesized with binary mixtures of surfactants were more stable during heating at high temperatures than those synthesized with a cationic surfactant alone.

Mesostructured V-Mgoxides were synthesized using the surfactant cetyltrimethylammonium bromide (CTAB) as template, V2O5, V(acac)3 (vanadium acetylacetonate), or NH4VO3 as vanadium source, and Mg(NO3)2, MgCl2, MgSO4, (MgCO3)4
