synthesis of iron oxide nanorods and nanocubes in an imidazolium ionic liquid

... Conclusion In conclusion, nanorods, nanocubes and nanospheres of iron oxide have been synthesized in [BMIM][Tf 2 N] ionic liquid. Oleic acid plays an important role in the shape control of nanostructures. Oleylamine ... nanostructures. Oleylamine and 1,2-hexadecanediol are required co-surfactants in controlling the formation of nanorods of iron oxide. The...
