Synthesis of porous silicates [PDF]

, 1995
The issues of importance and future concern in the synthesis of porous silicates and porous materials that contain a large fraction of silica, e.g. zeolites and other crystalline molecular sieves, are reviewed. The thermodynamics of zeolite synthesis are

Remediation of amoxicillin-contaminated water using zeolite from coal bottom ash

Sains Tanah: Journal of Soil Science and Agroclimatology
The contamination of antibiotics in water bodies has increased significantly in recent years. Various treatments, including adsorption, have been sought, but most include expensive sorbent material with low efficiency.

Phase Transformation of Zeolite P to Y and Analcime Zeolites due to Changing the Time and Temperature

Journal of Spectroscopy, 2013
In the present study, the synthesis of template free zeolite P under hydrothermal condition was investigated. The effects of parameters such as Si/Al ratios (3–45), crystallization temperatures (80–160°C), and cry (40–60 h) on the synthesis of zeolite P ...

A Most Unusual Zeolite Templating: Cage to Cage Connection of One Guest Molecule [PDF]

, 2010
An unusual case of a diquaternary ammonium dication, with large bulky end groups built from the tropane moiety and connected by a C4 methylene chain, is found to reside in zeolite SSZ-35 (STF).
