A novel method for synthesizing one or two-dimensional metal oxide (hydroxide) nanomaterials using deep eutectic solvents
NEW JOURNAL OF CHEMISTRY(2023)
Abstract
Deep eutectic solvents are utilized as green solvents to generate nanomaterials as they are less toxic and more cost-effective than conventional solvents. Contrary to a DES as a medium, metal-based DESs were employed as raw materials and media to fabricate one- or two-dimensional nanomaterials. FeO(OH) with a rod-bundle structure, Co(OH)(2) with a plate-like structure, ZnO with a rod-like structure, and CuO with a wedge-like nanoplate have been successfully synthesized. A possible mechanism for formation is also discussed. Moreover, the nanomaterials obtained exhibit low band gaps compared to bulk materials, increasing their ability to degrade organic and inorganic pollutants effectively. According to electrochemical tests, Fe2O3 nanoparticles have a high specific capacity and cycle stability, making them promising anode materials for NiFe rechargeable batteries.
