“…The nanopores of GO allows water to pass exclusively, while it is impermeable to other chemical species including helium 45 . Other than graphene, composite membranes based on zeolite also have been applied for water desalination [46][47][48][49] . Molecular dynamics simulation study suggested that zeolite with pore size comparable to the first hydrated shell diameter of chloride can be expected to improve salt rejection rate 47 .…”

Nanoscale materials are currently an attractive research subject because their properties are in contrast to their macroscopic counterparts. An inert material, such as bulk platinum metal for example, is known to exhibit a catalytic properties when its size is reduced into nanoscale. A stable material can become flammable or combustible, such as aluminum, and isolator material can become a conductor. Many attractive quantum phenomena also arise from reducing a material size into nanoscale dimensions. This review article discusses the concept, synthesis, and characterization of organic and inorganic nanolayered and nanoporous materials; and their application to catalysis and adsorption processes. Past achievements and future perspectives in the field of nanomaterial researches will be discussed as well. Furthermore, in the era of green chemistry, nanomaterials with all their derivatives are also required to have sustainable characteristics, such as biodegradable and renewable; which emphasizes that the development of nanomaterials in the framework of green chemistry should always be a priority. Through the synthesis of novel and functional nanomaterials using natural and local-based materials around us that are environmentally friendly and relatively easy to be obtained, our goal toward the inheritance of a greener world for the future generations is not an impossible dream.

Unlike conventional aluminosilicate zeolites synthesized in alkaline media, aluminophosphate molecular sieves (AlPOs) have always been prepared under acidic conditions in the past three decades; this has been regarded as one of essential factors for synthesis, except for the case of silica‐substituted analogues (SAPOs). For the first time, we demonstrate herein a simple and generalized route for synthesizing various types of aluminophosphate molecular sieves in alkaline media. A series of aluminophosphate sieves and their analogues have been prepared with different quaternary ammonium cations as structure‐directing agents in this manner. The above successes have extended the systematic media from acidic or neutral to alkaline for the preparation of a series of aluminophosphate molecular sieves, which possibly open an alternative route for the synthesis of aluminophosphate molecular sieves.

“…It can be seen that they have been continuously taken into account; indeed, researchers’ attention to them for such purposes is increasing. To date, zeolites have been considered for different membrane separation applications such as gas separation [ 15 ], pervaporation [ 16 , 17 , 18 ], microfiltration [ 19 ], ultrafiltration [ 20 ], nanofiltration [ 21 ], desalination [ 22 ], water treatment [ 23 , 24 ], and membrane distillation [ 25 ]. Either natural or artificial, zeolites are used for these applications thanks to their unique ion-exchange [ 26 ], adsorption, catalytic, and molecular sieving features.…”

Membranes, as perm-selective barriers, have been widely applied for gas separation applications. Since some time ago, pure polymers have been used mainly for the preparation of membranes, considering different kinds of polymers for such preparation. At this point, polyimides (e.g., Matrimid®5218) are probably one of the most considered polymers for this purpose. However, the limitation on the performance relationship of polymeric membranes has promoted their enhancement through the incorporation of different inorganic materials (e.g., zeolites) into their matrix. Therefore, the aim of this work is to provide an overview about the progress of zeolite embedding in Matrimid®5218, aiming at the preparation of mixed matrix membranes for gas separation. Particular attention is paid to the relevant experimental results and current findings. Finally, we describe the prospects and future trends in the field.
