Synthesis and Characterization of Zinc Phosphates in Aqueous and Non-Aqueous Media with (2-Hydroxyethyl) Trimethyl Ammonium Hydroxide as Template

Abstract

Zinc phosphate molecular sieve were synthesized using zinc chloride, phosphoric acid as a zinc and phosphor source, respectively. Different types of zinc phosphates zeolites were synthesized by conventional hydrothermal (using (2-hydroxyethyl) trimethylammonium hydroxide (2-HETMAOH) as new template. Also, ethylene glycol (EG) was utilized as co-solvent and ultrasonic tool was applied as mixer. The influence of the chemical composition of the starting sol-gel and the other parameters such as, Zn/P mole ratio, time of microwave irradiation were studied.
