A novel confined-space synthesis method has been developed to synthesize zeolite nanocrystals. Colloidal silica nanoparticles serving as the silica source as well as the hard template were embedded in the mesoporous carbon via in situ polymerization of furfuryl alcohol (FA) in the presence of tri-block copolymer (Pluronic P123), and then reacted with an alkaline aqueous solution (Na2O-Al2O3-H2O...

In the present work, the nano-NaX zeolite and micro-NaX zeolite were synthesized via hydrothermal method. Then, the adsorption capacities and isotherms of pure gases CO2 and CH4 on the synthesized zeolite nanoparticles were determined at three temperatures of 288, 298 and 308 K and various pressures from 1 up to 20 bar. Adsorption capacities of CO2 on the nano-sized zeolites NaX were showed to ...

The Nano-CrY zeolite synthesized and characterized by Fourier transfer infrared (FT-IR), X-ray diffraction (XRD),and Scanning electron microscopy (SEM).The result show that nano catalyst prepared with mainly particles size about 30-80 nm .The XRD show the structure of the zeolite does not collapse. This Nano-CrY zeolite has been used as new, and nontoxic catalyst for catalyzes of synthesis of 2...

The zincZeolite Socony Mobil-Five nano-particles (Zn-ZSM-5 NPs) composite was prepared and applied successfully as a new coating material to improve the corrosion resistance of steel. The corrosion type and quality of both pure zinc and our new coating material, Zn-ZSM-5 NPs, were studied using mass loss, impedance and electro-chemical polarization techniques in a sodium chloride solution. Obta...

GIS-NaP1 zeolite samples were synthesized using seven different Si/Al ratios (5-11) of the hydrothermal reaction mixtures having chemical composition Al2O3:xSiO2:14Na2O:840H2O to study the impact of Si/Al molar ratio on the water vapour adsorption potential, phase purity, morphology and crystal size of as-synthesized GIS-NaP1 zeolite crystals. The X-ray diffraction (XRD) observations reveal tha...

a pebax-nano zeolite x mixed matrix membrane was fabricated and operationally characterized using single gas (co2) permeation. x-ray diffraction (xrd) analysis was used to study the arrangement of polymer chains of mixed matrix membrane. the membranes were characterized by scanning electron microscopy (sem) to study cross-sectional morphology. the single gas permeability were carried out for ne...

in this research, zeolite a was synthesized from waste porcelain and cds nano-particles were doped in zeolite framework by a precipitation after an ion exchanging process. all raw and modified samples were characterized by ft-ir, xrd and sem methods. primary experiments showed that the good efficiency of loaded nano cds onto the zeolite a for photodecomposition of dimethyldisulfide (dmds) under...

Novel core-shell composites have been developed by immobilization of non-luminescent europium(III) complexes onto the surface of silica shells that are coated on the surface of luminescent dye-loaded zeolite L nano-crystals. The obtained core-shell composites were used for the ratiometric detection of dipicolinic acid (DPA) molecules. The dyes located in the channels of the zeolite L host are p...

mfi zeolite membranes were prepared on porous α-alumina substrates, using secondary growth of nano-seeded layers. the resulting membranes were characterized by means of scanning electron microscopy (sem), x-ray diffractometry (xrd), and pervaporation performance tests for separation of benzene, toluene and xylene (btx) mixture from contaminated water. the morphology, thickness, homogeneity, cry...
