Abstract: Nanostructured metal oxides/ chalcogenides with various morphologies viz., particles, wires, rods, tubes, plates etc., in thin films have been significantly envisaged in various energy storage and conversion device technologies including thin film transistors, photoelectrochemical cells, heterojection-based solid-state solar cells, polymer solar cells, gas sensors, dye-sensitized solar cells, batteries and supercapacitors etc. To suffice requirements of devices, novel cost-effective nanostructures have been synthesized and successfully evaluated. Since single component metal oxide/form cannot satisfy all essential requisites for a specific energy device, so emphasis has been made to synthesize property oriented nanostructures to provide a much-needed functionality. For example when one wish to use metal chalcogenide/oxide as counter electrode like platinum, then synthesized nanostructures of NiS, CoS, FeO3 etc., should necessarily possess catalytic properties. In this talk, the benefits of solution-processed metal oxide/ chalcogenides nanostructures in the areas of energy (conversion and storage), chemical sensors along with synthesis approach will be discussed. Moreover, biological applications including protective antigen detection and antibiotics in addition to gas sensors and supercapacitors will be highlighted.
Attempt will be made cover up the topic with an importance of these nanomaterials in assembling integrated energy conversion and storage device technologies.
