Synthesis and Characterization of Nickel Phosphate Nanoparticles and VSB-5 with Quaternary Ammonium Base

Nickel phosphate VSB-5 (Versailles Santa Barbara-5) was synthesized with microwave for 1 h and followed by conventional oven for 2 days in the presence of (2-hydroxyethyl) trimethylammonium hydroxide as template. By addition of ethylene glycol, nickel phosphate nanoparticle was prepared with average size of 55 nm. Also, nickel phosphate nanoparticles was synthesized by microwave assisted hydrothermal using tetrapropylammonium hydroxide as template. The spherical nickel phosphate crystals with average diameter of 80 nm were successfully synthesized in the presence of tetrapropylammonium hydroxide. Furthermore, spherical nanosized crystals were prepared with polyethylene glycol: water volume ratio of 1:1 using (2-hydroxyethyl) trimethylammonium hydroxide as template.
