Abstract—The crystallization of aluminophosphate gels prepared using aluminum isopropoxide with di‑n-propylamine/Al₂O₃ was equal to 1.0, 1.4, and 1.8. It has been shown that changing the template/Al₂O₃ ratio in reaction gels leads to the formation of various intermediate phases during crystallization into the AlPO₄-11 molecular sieve. A method for controlling its secondary porous structure based on regulating the template/Al₂O₃ ratio is proposed in reaction gels.

摘要-用二正丙基胺/Al2O3 与异丙醇铝制备的磷酸铝凝胶的结晶比例分别为 1.0、1.4 和 1.8。研究表明，改变反应凝胶中模板/Al2O3 的比例会导致在结晶成 AlPO4-11 分子筛的过程中形成各种中间相。提出了一种基于调节反应凝胶中模板/Al2O3 比例的二级多孔结构控制方法。
