摘要
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AlPO4-5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CeAPO-5分子筛的比表面积。
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 and.The obtained structure was similar to that of AlPO4-5.The incorporation of Ce(Ⅲ) ions into the framework did not change the AlPO4-5 structure,but did,however,increase the surface area.
