新型分子筛CeAPO-5的合成及表征

采用水热合成法，以拟薄水铝石，正磷酸，碳酸铈，水为原料，三乙胺为模板剂合成了新型CeAPO-5分子筛。利用XRD、FT-IR、SEM和BET等手段对它的晶体结构、表面形貌做了系统的表征。结果表明CeAPO-5分子筛具有AlPO-5分子筛的晶体结构。Ce（III）的引入并没有改变分子筛的骨架结构。但会增加新型分子筛CeAOP-5分子筛的比表面积。

Synthesis and characterization of cerium aluminophosphate molecular sieve(CeAPO-5)

Cerium (III) aluminophosphate molecular sieve has been synthesized starting from pseudo-boehmite , phosphoric acid, cerium carbonate, and water, in the presence of a triethylamine organic template. Based on the synthesized material, many of characterization were carried out by XRD, FT-IR, SEM, BET methods. It shows that the material has a tetrahedral framework of APO4] and PO4].The obtained structure was similar to that of AlPO-5. The incorporation of Ce (III) ions into the framework did not change the AlPO-5 structure, but did, however, increase the surface area.
