Impact of Zeolite from Coal Fly Ash on Soil Hydrophysical Properties and Plant Growth

Agriculture, 2022
Zeolites can be extensively employed in agricultural activities because they improve soil properties such as infiltration rates, saturated hydraulic conductivity, water holding capacity, and cation exchange capacity.

Formation and characterization of inorganic membranes from zeolite-silica microcomposites [PDF]

, 1988
Small crystals of zeolites (500-1000 nm) with two- and three-dimensional channel systems (faujasite and ZSM-5 structures) were embedded in amorphous thin films derived from TEOS hydrolyzed in alcoholic solution.

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

Advanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

The Exchange Mechanism of Alkaline and Alkaline-Earth Ions in Zeolite N

Molecules, 2019
Zeolite N is a synthetic zeolite of the EDI framework family from the more than 200 known zeolite types. Previous experimental laboratory and field data show that zeolite N has a high capacity for exchange of ions.

Transformation of heulandite type natural zeolites into synthetic zeolite LTA

Environmental Technology & Innovation, 2021
Abstract This study developed an approach to synthesise zeolite LTA from three different natural heulandite class zeolite deposits (Escott, Avoca, and NextSand). The challenge was to determine the impact of pre-activation of clinoptilolite or heulandite materials upon the synthesis of zeolite LTA. Heulandite (Escott; Avoca) was thermally less stable (

Analysis of the textural characteristics and pore size distribution of a commercial zeolite using various adsorption models [PDF]

, 2011
Analysis of the textural characteristics and pore size distribution of a commercial zeolite (Sigma Aldrich, product No. 96096) have been conducted experimentally using a surface analyzer by measuring the N2 adsorption isotherm at 77 K. The resulting data

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

Advanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...
