摘　　要： 采用原位水热合成法在多孔α-Al2O3上制备了连续致密的CoAPSO-5分子筛膜,并考察了Co含量对成膜过程的影响机制。通过XRD、SEM及ICP检测,证明所合成的为致密、均一、无取向CoAPSO-5分子筛膜,同时分析了合成液中进入分子筛的Co含量及其对CoAPSO-5分子筛膜的晶形、厚度及完备性的影响,并通过气体渗透法验证所合成的分子筛膜为无缺陷的。 The continuous and highly intergrown CoAPSO-5 membranes were synthesized on the α-A1203 substrates by in situ crystallization, which was studied focused on effect of Co content. According to the characterization of scanning electron microscopy （SEM） , X-ray diffraction （XRD） and inductive coupled plasma emission spectrometer （ICP）, the zeolite membranes were composed of well-intergrown CoAPSO-5 crystals, which lost their own morphology and tightly covered on the α-A1203 substrate in random orientation. Meanwhile, the Co content of the CoAPSO-5 crystal and its influence on the morphology, the thickness and the completeness of CoAPSO-5 membranes were studied. The gas permeation measurement revealed the resulting membranes were of high-quality with few non-zealitic pores.
