Zeolite FAU type-Y is one of the most studied framework of all zeolites, and has been used as catalysts for number of reactions in the refinery and petrochemical industry. In this research, nanocrystalline zeolite Y was synthesized by hydrothermal method. The crystal size of zeolite Y is influenced by temperature, aging time, alkalinity, and water content. The synthesized zeolite NaY is identif...

The goal of the present work is the design of a material that may act as a robust and low cost biosorbent fortreatment of wastewater with low concentration of metals ions, such as chromium and iron. The removal ofmetallic ions from binary aqueous solutions of Fe(III)/Cr(III) and Fe(III)/Cr(VI), by an Arthrobacter viscosusbiofilm supported on NaY zeolite was investigated. Experiments...

Composite molecular sieves, FAU/SBA-15, having core-shell structure were synthesized. The synthesized composite sieves were characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), pyrolysis fourier transform infrared (Py-FTIR) spectroscopy, temperature programmed desorption spectra (NH3-...

Mechanochemical activation and steam-assisted interzeolite transformation offer a simple, fast cost-efficient synthesis route to gmelinite (GME) zeolite. The use of faujasite (FAU) as the parent zeolite precursor facilitates reaction results in high yields high-quality GME less than 20 h under optimized conditions. accessible porosity amounts stacking-faults were determined by N2 physisorption ...

A facile and rapid photochemical method for preparing supported silver nanoparticles (Ag-NPs) in a suspension of faujasite type (FAU) zeolite nanocrystals is described. Silver cations are introduced by ion exchange into the zeolite and subsequently irradiated with a Xe-Hg lamp (200 W) in the presence of a photoactive reducing agent (2-hydroxy-2-methylpropiophenone). UV-vis characterization indi...
