controlled crystallization of lta zeolitic nanoparticles from a clear solution using organic template
نویسندگان
چکیده
lta zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. the as-synthesized lta zeolite particles were characterized by powder x-ray diffraction (xrd) analysis, scanning electron microscopy (sem), fourier transform infrared (ft-ir) spectroscopy, energy dispersive x-ray (edx) analysis and surface area measuring technique of brunauer, emmett and teller (bet). xrd patterns and ft-ir spectra were ascertained the formation of pure crystalline phase of 4a (i.e. lta) zeolite. sem micrograph was shown particles size in the range of 60 -170 nm with uniform morphology. the si /al ratio of the as-synthesized zeolite nanoparticles was 1.66 with a bet surface area of 421 m2/g.

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,...

متن کاملRemoval of Lead from Aquatic Solution Using Synthesized Iron Nanoparticles
Due to its ability in chemical oxidation of contaminants, iron nanoparticle is a material of choice to remove lead ions from aquatic solutions. In this study a reduction method in solution phase was applied to synthesize thenanoparticles. Afterwards, the size of the synthesized particles were confirmed by Scanning Electron Microscopy. It is worth noting that th...
متن کاملArsenic Removal from Aqueous Solution Using Titanium Dioxide Nanoparticles (Anatase)
Background and Objectives: Groundwater sources, as strategic sources of water supply, are of particular importance for human beings. Arsenic is a toxic and carcinogenic contaminant that has been reported to be widely found in groundwater sources. In recent years, adsorption property of nanoparticles has been used to remove arsenic. The present study was performed with the aim of assessing the a...
متن کاملTemplate synthesis of gold nanoparticles with an organic molecular cage.
We report a novel strategy for the controlled synthesis of gold nanoparticles (AuNPs) with narrow size distribution (1.9 ± 0.4 nm) through NP nucleation and growth inside the cavity of a well-defined three-dimensional, shape-persistent organic molecular cage. Our results show that both a well-defined cage structure and pendant thioether groups pointing inside the cavity are essential for the Au...
