Synthesis and characterization of nanoporous monetite which can be applicable for drug carrier

Abstract

Wormhole-like mesostructured monetite was successfully synthesized using cetyltrimethylammonium bromide (C19H42BrN, CTAB), as a porosity agent. X-ray techniques and FTIR reveal that the crystalline grains consist of highly crystalline pure monetite phase. Monetite rods with diameter around 20-40 nm and length in the range of 50-200 nm were confirmed by FESEM and TEM. Based on N2 adsorption-desorption isotherms investigation, surface area increased up to 31.5 m2/g due to the removal of surfactant after calcinations at 400°C. The results indicate that CTAB can not only affect monetite crystallization but also change particles morphology from plate shape to rod-like. © 2012 Esmael Salimi and Jafar Javadpour.
