loaded zeolite organic. Development of Platinum-Loaded Y. developed. This research aims to develop new zeolite-based catalysts for highly efficient liquid phase conversion of carbohydrates to H2. Particulate platinum-loaded Y-type zeolite (Pt/NaY) catalysts have been synthesized, characterized, and evaluated for H2 production from methanol.
Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.
Ce(IV)-loaded Y-zeolites (CeY) were prepared for selective removal of the trace amount of organic sulfur compounds from hydrodesulfurization (HDS)-treated diesel oil. The CeY samples can be obtained from NH 4 –Y-zeolite (NH 4 Y) using liquid-phase ion-exchange and solid-state ion

1. Introduction. Among small-molecule metabolites that are emitted from the human body, organic volatiles have great potential as biomarkers for the early detection and treatment of diseases, particularly cancer .For instance, the detection of volatile organic compounds (VOCs) in blood samples or the headspace of cancer cells, and consequently in exhaled breath , , is an emerging approach for ...
Zeolite is composed of porous crystals of silicon and aluminum, and the material can be loaded with other ions such as sodium, potassium, calcium, and magnesium. The most common forms that farmers might see are sodium silico-aluminate (SSA), calcuim aluminosilicate (CAS) and hydrated sodium calcium alumino-silicate (HSCAS).
18-4-2003· Organic-inorganic hybrid zeolite materials containing an organic framework have been synthesized by partially superseding a lattice oxygen atom by a methylene group. The use of methylene-bridged organosilane as a silicon source gives zeolite materials containing an organic group as lattice (ZOL), with several zeolitic phases such as the MFI and the LTA structures.
Phosphine (PH3) is a highly toxic air pollutant commonly used in the semiconductor and optoelectronic industries, but it has received less research attention due to its handling difficulty. In this study, metal (Cu, Zn, or Mn) loaded ZSM-5 and Y zeolite adsorbents are first prepared for the adsorption of PH3 toxic gas. The physical and chemical properties of the adsorbents which influence the ...
The Ce–Y-zeolite exhibits higher selectivity for the adsorption of the organic sulfur compounds, the sulfur adsorption amount of the Ce–Y-zeolite is strongly dependent on preparation conditions of the adsorbent, and the sulfur contents can be reduced to less than 0.1 ppm by using the adsorbent.

An initial concentration 200mgL^-1 of ACE was used for the zeolite granules adsorption process. After 120 hours of loading, the gaseous O3 based process was applied to regenerate the ACE loaded zeolite granules. It was found that an ideal ACE degradation rate of 80 -100% was obtained by drying the zeolite granules before the regeneration.
Polyoxometalate (POM) catalysts with different trivalent hetero ions (Mn+ = Fe3+, Al3+, and Cr3+) were prepared by incipient wetness impregnation method and supported on different zeolites namely, NaY, ZSM-5 and Mordenite. The intended catalysts samples were distinguished by X-ray diffraction, FTIR and surface texture measurements. The data given disintegration in the crystallinity of zeolite ...
Versatile zeolite (clinoptilolite) is used in many ways to remove toxic pollutants.Heavy metals such as mercury, lead, aluminium and cadmium, volatile organic compounds and radionuclides are drawn into the structure of each superfine zeolite particle where they are captured and permanently bonded.
Mg−Cu‐loaded β‐zeolite was prepared as an acid−base bifunctional catalyst for the conversion of furfural to monoaromatic compounds. It is found that this catalyst exhibited high selectivity towards benzene, toluene and xylenes (BTXs) production with anti‐polycyclic‐aromatic‐hydrocarbon formation as well as anti‐coking ability when compared with Cu‐loaded β‐zeolite and the ...

Metal–organic frameworks (MOFs) are a class of compounds consisting of metal ions or clusters coordinated to organic ligands to form one-, two-, or three-dimensional structures. They are a subclass of coordination polymers, with the special feature that they are often porous.The organic ligands included are sometimes referred to as "struts", one example being 1,4-benzenedicarboxylic acid (BDC).

Porous materials combining high hydrophobicity, large surface area, as well as large and uniform pore size are very useful but rare. The nanoporous zeolitic metal azolate framework, RHO-[Zn(eim)2] (MAF-6, Heim = 2-ethylimidazole), is an attractive candidate but thought to be unobtainable/unstable. In this work, the supramolecular isomerism of [Zn(eim)2] is thoroughly studied using a rapid ...
