Ionic liquid- assisted formation o f Co۳O۴ nanopartic les

Nanosized transition metal oxides oft en exhibit enhanced p hysical, ch emical, the rmal, electrical, optical, or magnetic properties. A good e xample is crystalline c obalt oxide with nanom eter-scale, an advanced material with wide potential a pplications as heterogeneous catalysis, Li-ion r echargeable batteries and so on. Traditional methods for the synthesis of Co۳O۴ need some special in struments, harsh conditions, and relatively h igh perfor mance temperature. Therefore, there is a need f or more effo rt towards the preparation of the spinel- type nano Co۳O۴ [۱]. Ionic liquids seem to be w ell position ed to addr ess the challenge of preparing Co۳O۴ nanoparticles, du e to their negligible v apour pressure, recyclability, exte nded temperature range in the liqui state, low toxicity, high ionic con ductivity, a wide range of viscosities and high chemical an d thermal st ability. In re cent years, ionic liquids have been discovered to be excellent media i n the formation and stabilization of metallic or metal oxide nano -sized objects [۲].
