HOTPLATE TECHNIQUE FOR NANOMATERIALS

As an efficient and cost-effective method to synthesize nanomaterials, the hotplate technique has been reviewed in this article. Systematic studies have been carried out on the characterizations of the materials synthesized. In addition to the direct preparation of nanomaterials on metals, this method has been extended to the substrate-friendly and plasma-assisted hotplate synthesis. Apart from chemically pure nanostructures, a few nanohybrids were synthesized, further demonstrating the flexibility of this technique. The investigations on their applications indicate that they are promising material systems with potential applications in field emission devices, gas sensors, Li-ion batteries and ultrafast optical devices.
