aThe latest developments in zeolite membranes are reviewed, with an emphasis on the synthesis techniques, including seed assembly and secondary growth methods. This review also discusses the current industrial applications of zeolite membranes, the feasibility of their use in membrane reactors and their hydrothermal stability. Finally, zeolite membranes are compared with metal-organic framework (MOF) membranes and the latest advancements in MOF and mixed matrix membranes are highlighted.

ÖZBu çalışmada farklı sentez koşullarında ve iki farklı çinko tuzu ile ZIF-L bazlı kristaller ve membranlar sentezlenmiştir. Sentezlenen membranların He, N2 ve CO2 gazı geçirgenliği ve ideal seçicilik ölçümleri gerçekleştirilmiştir. 0,3-2x10 -6 mol/m 2 .s.P aralığında elde edilen gaz geçirgenliği değerleri artan sentez sıcaklığı ve çinko nitrat yerine çinko klorür kullanımı ile artmıştır. Difüzyon hücresi ile sentezlenen membran ise vakum filtrasyon-ikincil büyüme ile sentezlenen membrana göre daha düşük gaz geçirgenliği değerleri göstermiştir. Çalışma kapsamında kullanılan sentez koşullarında difüzyon hücre sisteminde çinko klorürür ile sentezlenen membranın gaz geçirgenliği ve seçiciliğinde optimum performansa sahip olduğu tespit edilmiştir.Anahtar Kelimeler: Zeolitik imidazolat iskelet, ZIF-L, membran, difüzyon hücresi. ABSTRACT In this study, ZIF-L based crystals and membranes were synthesized with different zinc precursors at different synthesis conditions. The determination of the permeation and ideal selectivities for He, N2 and CO2 gases was performed with the stynthesized membranes. Gas permeation values obtained in the 0.3-2x10-6 mol/m 2 .s.P range increased with increasing synthesis temperature and by using zinc chloride instead of zinc nitrate. The membrane synthesized in the diffusion cell possessed lower gas permeance values compared to the one sytnesized with vacuum filtration-secondary growth method. The membrane synthsized with zinc chloride in the diffusion cell showed optimum performance in gas permation and ideal selectivity considering the synthesis conditions used in the context of this study.
