“…In the last two decades, substantial progress towards this goal has been made, so that to date some of the zeolite membranes are already used on industrial scale. 180,181 Zeolite membranes are synthesized by introducing ex situ prepared crystal seeds on a porous substrate and further in situ growth of the zeolite layer. 181 This procedure leads to the formation of a structure composed of multiple micrometer sized crystallites ( Figure 28).…”

This composite structure inevitably has numerous defects-most prominently intercrystalline spaces, which are larger than the zeolite pores.…”

When a solid surface accommodates guest molecules, they induce noticeable stresses to the surface and cause its strain. Nanoporous materials have high surface area and, therefore, are very sensitive to this effect called adsorption-induced deformation. In recent years, there has been significant progress in both experimental and theoretical studies of this phenomenon, driven by the development of new materials as well as advanced experimental and modeling techniques. Also, adsorption-induced deformation has been found to manifest in numerous natural and engineering processes, e.g., drying of concrete, water-actuated movement of non-living plant tissues, change of permeation of zeolite membranes, swelling of coal and shale, etc. In this review, we summarize the most recent experimental and theoretical findings on adsorption-induced deformation and present the state-of-the-art picture of thermodynamic and mechanical aspects of this phenomenon. We also reflect on the existing challenges related both to the fundamental understanding of this phenomenon and to selected applications, e.g., in sensing and actuation, and in natural gas recovery and geological CO2 sequestration.

“…An important consideration on the way for industrial application might be the availability of membranes characterized by suitable performances at reasonable prices. On the one hand, a 10,000 m 2 /year production line for LTA membranes was established [48]. In this context,the further up-scaling also of other membrane types will be of significant importance whether zeolite membranes will be applied in industrial catalysis or not.…”

Literature on zeolite membranes in catalytic reactions is reviewed and categorized according to membrane location. From this perspective, the classification is as follows: (i) membranes spatially decoupled from the reaction zone; (ii) packed bed membrane reactors; (iii) catalytic membrane reactors and (iv) zeolite capsuled catalyst particles. Each of the resulting four chapters is subdivided by the kind of reactions performed. Over the whole sum of references, the advantage of zeolite membranes in catalytic reactions in terms of conversion, selectivity or yield is evident. Furthermore, zeolite membrane preparation, separation principles as well as basic considerations on membrane reactors are discussed.

“…Thus, the fabrication of MOF membranes needs to be well-designed, although MOF powders can be prepared easily by hydrothermal or solventhermal method. Up to now, there are several reviews summarizing the various strategies for MOF membranes synthesis in detail [66,84,85]. Here in this review, hence, only the membrane synthesis methods employed in the last three years will be discussed.…”
