Specific Ionic Liquids for the Synthesis of Acicular Goethite Nanoparticles

Abstract

Now-a-days preparation and study of nano particles has gain significant consideration. The common theme here is always "size matters" and over the last decades, researchers have developed exciting new materials with unique and tuneable properties. Among wide spread fields in this area, we focused on the synthesis and study of ferromagnetic iron oxides (acicular goethite) which has different application in various magnetic tapes and medical monitoring. We report synthesis of acicular goethite by using ionic liquid as a solvent and as an oxidant. With the help of [BMIM]ClO₃ the reaction time was decreased from 6 h to 2 h and oxidation reaction was took place at the lower temperature (changing from 60 ºC to 40 ºC).
