This review focuses on the synthesis, crystallization mechanism, and application of colloidal zeolites. The synthesis formulations features different zeolite-type structures prepared in nanosized form are summarized. Special attention is paid to zeolites as stable suspensions. Next, new insights into zeolite mechanism gained by using model systems discussed. Further, methods for deposition nanocrystals from suspensions onto supports shapes compositions used fabrication films membranes...
The oxygen reduction reaction (ORR) activity of carbonized ZIF-8 (CZ) and its Fe-doped derivatives, CZ-A (doped with ammonium iron (II) sulphate) CZ-B acetate), were examined in both acidic (0.5 M H2SO4) basic (0.1 KOH) electrolytes using a rotating disk electrode setup. These data show that the ORR catalysts is higher than pure CZ, electrolyte. Extensive materials characterization highlights important differences sample crystallinity, morphology, porosity, chemical composition as function...
This study reports the seeded synthesis of MFI‐type (ZSM‐5) zeolite in fluoride medium at pH = 8.5. Crystal growth kinetics resulting (ZSM‐5‐F) as a function seed content and crystallization temperature is studied. The time reduced to 1.5 h crystals with sizes below 200 nm Si/Al ratio 23.6 are obtained. A similar characteristics but synthesized hydroxyl (ZSM‐5‐OH) used evaluate ZSM‐5s different media. Their physicochemical properties compared particular attention paid nature, number,...
Zeolite A nanoparticles were synthesized under room-temperature conditions from a very reactive organic-template-free gel system. The optimization of the syntheses parameters, namely, composition initial system and careful choice reactants, allowed crystallization to be accomplished within 3 days. At this stage individual zeolite crystals in range 100−300 nm without well-developed crystal faces. prolongation synthesis time up 10 days led formation larger well-faceted cubic averaging about...
The confinement of silver ions and nanoparticles within ultrasmall EMT zeolite (Ag<sup>+</sup>-EMT Ag<sup>0</sup>-EMT samples) qualitative comparison their antibacterial properties are reported.
A ZnO@ZIF-8 powder on a gram scale was prepared via treatment of ZIF-8 with silver nitrate to induce spontaneous formation ZnO nanorods the surface crystals. The crystal structure, phase purity, and physicochemical characteristics were determined by X-ray diffraction, high-resolution electron microscopy, energy-dispersive spectroscopy, nitrogen adsorption. antimicrobial potential for reduction microorganisms often implicated catheter-associated urinary tract infections (CAUTIs) studied in...
Nanosized small-pore zeolites RHO and MMU-1 (a new Cs-Na modification of an EDI-type zeolite structure) were prepared in the presence cesium hydroxide by changing molar composition precursor solution. XRD, Raman, FTIR results indicated that Cs had a structure-directing effect controlled formation respective phases. The water played crucial role, when amount was under certain level, cancrinite formed. Solvent-free syntheses attempted, confirmed conclusions drawn based on water-mediated...
Graphene oxide (GO) membranes hold significant promise for the water purification. However, they also face problem of structural swelling, which limits their use in treatment applications. In this work, a novel dual-modulated core-shell metal-organic framework@Chitosan (MOF@CS) was successfully synthesized and used as an intercalation cross-linker to optimize interlayer spacing stability GO membranes. Molecular dynamics simulation confirms that MOF@CS, acting intercalator, accelerates...
The development of procedures for the synthesis nanosized zeolites from cheap sources in absence organic templates is great industrial importance. In this work, size FAU-type was decreased micron- to nano-dimensions by reducing amount distilled water added fly ash after alkali fusion. showed high antimicrobial activity introduction Cu and Ag, which associated with release Cu/Ag into medium. This Cu-containing similar prepared conventional methods but lower than that Ag-containing zeolites.
AlPO4-18 layers were prepared on Si wafers via spin-coating or the Langmuir−Blodgett (LB) method using nanosized crystals. Multilayers deposited by spin-coating, whereas seeds assembled LB technique monolayers. The seeded not stable upon secondary growth under microwave radiation, and no films formed supports. Dense could be obtained after stabilization of seed adding prehydrolyzed tetraethylorthosilicate (TEOS) to colloidal suspension prior support seeding. stabilized grown stable....
