Anodization of WO3 nanorods in the presence of citric acid [Dataset]

In this study, WO3 nanorods have been fabricated by simple anodization in the presence of different amounts of citric acid and at different anodization times. A comprehensive morphological, structural, electrochemical and photoelectrochemical characterization of different samples has been carried out. Moreover, a formation mechanism for WO3 nanorods has been proposed. Finally, these nanostructures have been proven to be excellent visible-light photoelectrocatalysts to remove persistent organic pollutants present in wastewaters, such as fenamiphos. Almost the 80% of this molecule was eliminated from the test solution after 180 min of irradiation, indicating the great potential of these WO3 nanorods, fabricated following a very simple and unexpensive procedure, in the energy and environmental fields as photoelectrocatalysts. File List: - EIS: Electrochemical Impedance Spectroscopy test were performed to study the electrochemical properties of the nanostructures. - Current density transient: Current density transients recorded during anodization of every sample. -MS: MS tests are used to determine the semiconductor type and estimate the charge carrier density from the capacitance–potential relationship. -Nanostructures light pulses: Recording the photocurrent as a function of time allows the evaluation of the stability of the nanostructures by monitoring the persistence of the photoresponse under illumination. -UV-Vis_Degradation (Folder):UV-Vis spectra are used to monitor the decrease in a compound’s absorbance over time.
