“…Z3 synthesis is based on the crystallization of silica on an ammonium salt (TPABr). The aqueous solutions with chemical compositions of SiO 2 :TPABr:H 2 O:NaOH = 1:0.25:40:0.3 led to silicalite-1 crystallization after hydrothermal treatment (453 K) [ 27 ].…”

In this paper, the sorption of NH3, H2O, SO2 and CO2 was tested for several selected inorganic materials. The tests were performed on samples belonging to two topologies of materials, faujasite (FAU) and framework-type MFI, the structures of which differ in pore size and connectivity. All sorbates are important in terms of reducing their emissions to the environment. They have different chemical nature: basic, alkaline, and acidic. They are all polar in structure and composition and two of them (ammonia and water vapor) can form hydrogen bonds. These differences result in different interactions with the surface of the adsorbents. This paper presents experimental data and proposes a mathematical description of the sorption process. The best fit of the experimental data was obtained for the Toth and GAB models. The studies showed that among the selected samples, faujasite has the best sorption capacity for ammonia and water vapor, while the best sorbent for sulfur dioxide is the MFI framework type. These materials behave like molecular sieves and can be used for quite selective adsorption of relevant gases. In addition, modification of the faujasite with organic silane resulted in a drastic reduction in the surface area of the sorbent, resulting in significantly lower sorption capacities for gases.

“…However, S-1 and 5GaN/S-1 display type I isotherms, indicating the presence of a significant amount of micropores in the samples. 35,36 Additionally, micropores exist in HS-1, 5GaN/HS-1, HNS-1, and 5GaN/HNS-1 samples. Different from the conventional hydrothermal preparation method, the samples exhibited clear hysteresis loops at P/P 0 > 0.4, indicative of the presence of a mesoporous structure.…”
