Goethite Nanofibers /CNTs based Nanocomposites Synthesized by Free-Template Hydrothermal Method and their Physico-Chemical Properties for Energy Storage Application

In this investigation, we report the synthesis of Goethite-NFs/CNTs nanocomposites using hydrothermal method at optimized growth condition. These nanostructured products have been characterized in order to identify their physico-chemical properties by different techniques, such as X-Ray Diffraction (XRD), Raman Spectroscopy, High Resolution Scanning Electron Microscopy (FESEM), Thermal analysis (TGA/DTA) and UV- Vis Spectroscopy. The obtained Goethite nanofibers (NFs) shown structured triangular base with diameter range [181 - 363 nm]. Using nested twisted CNTs (MWNTs type) but fairly homogeneous around 48 nm, formation an assembly two forms iron oxide Nanofibers) nanocomposite configuration confirms significant improvement properties, like increase electrical conductivity proven gap energy Eg from 3.12 2.50 eV. Consequently, reached results prove clearly that kind oxide-NFs/MWNTs based can be excellent candidate electroactive nanomaterials for storage application.
