| 摘 要： | 合成了钴取代磷铝酸盐分子筛CoAPO-11。考察了晶化温度和钴铝比等对CoAPO-11的合成及其性能的影响。采用X射线衍射(XRD)、扫描电子显微照片(SEM)、热重-差示热分析(TG-DTA)和测定BET比表面积法测定等对合成样品进行表征。结果表明，在一定的钴铝比范围内,能合成出结晶度和纯度较高的CoAPO-11分子筛； CoAPO-11分子筛的表观形貌为长条晶片的团状聚集体；CoAPO-11分子筛具有较好的热稳定性。 |

| Abstract: | Cobalt-substituted CoAPO-11 molecular sieves were synthesized by hydrothermal methods. The effects of Co/Al molar ratio and crystallization temperature on the synthesis and properties of CoAPO-11 were discussed. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric/differential thermal analysis (TG/DTA) and N_2-adsorption. The results showed that CoAPO-11 molecular sieves with higher crystallinity and purity could be synthesized under a certain Co/Al molar ratio; surface of the molecular sieves showed an agglomeration of bar-shaped crystals; the molecular sieves exhibited high thermal stability. |
| Keywords: | CoAPO-11 molecular sieve synthesis Co/Al molar ratio crystallization temperature |
