The continuous and highly intergrown SAPO-5 membrane on the alpha-Al2O3 substrate was synthesized by using in situ crystallization and microwave heating. According to the characterization using scanning electron microscopy (SEM) and X-ray diffraction (XRD), the 5 mu m-thick membrane was composed of well-intergrown pure SAPO-5 crystals, which were tightly covered on the alpha-Al2O3 substrate in random orientation. The single-component pervaporation measurements revealed the resulting membrane was of high-quality with few non-zeolitic pores. (c) 2008 Elsevier Inc. All rights reserved.
