摘要： 采用气相转移法在致密氧化铝陶瓷片上制备了ZnAPO-34薄膜,并用XRD和SEM对其进行了表征.结果发现,合成配方中水的含量对ZnAPO-34粉末和膜的晶体大小和形貌有很大的影响,而且对成功制备连续的ZnAPO-34膜至关重要.在固相配比为n(P2O5);n(Al2O3);n(ZnO);n(H2O)=1;0.8;0.4;150,液相为1;75(摩尔比)的三乙胺-水溶液中,于170℃反应24h的条件下,经重复合成可得到连续无缺陷的ZnAPO-34分子筛膜.

Abstract: ZnAPO-34 films on dense alumina plates were synthesized by the vapor-phase transport(VPT) method. XRD and SEM were used to examine the powders and films. The water content in the synthesis had a strong influence on the crystal sizes and the morphology of ZnAPO-34 powders and films, and played a critical role on the successful preparation of a uniform ZnAPO-34 film. The optimum VPT synthesis was conducted at 170 ℃ for 24 h with the gel prepared as a composition of n(P2O5);n(Al2O3);n(ZnO);n(H2O)=1;0.8;0.4 ;150 and the liquid phase composed of triethylamine and water [n(triethylamine);n(H2O)=1;75]. Repeated synthesis cycles were necessary to obtain a continuous and uniform ZnAPO-34 film.

Key words: Molecular sieve film, Vapor-phase transport method, ZnAPO-34 film
