Synthesis of anodized WO3 nanocatalysts using Melia azedarach leaves extract for energetic applications (Dataset)

This study reports the bio-mediated synthesis of tungsten trioxide nanostructures from aqueous extracts of Meliaazedarach (L.) dry leaves. The synthesis was carried out by electrochemical anodization of tungsten foils in thepresence of different volume percentages of leaves extracts. These nanostructures were afterwards characterized by X-Ray Diffraction (XRD), impedance measurements and linear sweep voltammetryin the presence of simulated solar light. Finally, these nanoelectrodes were used as(photo)electrocatalysts in the photoelectrochemical water splitting process to obtain green hydrogen and asanodes in Li-ion rechargeable batteries.
