[EN] The resulting solutions from the cotton fabrics dyeing using the trichromy Procion HEXL, with NaCl as electrolyte, were electrochemically treated. These dyes have two azo groups as chromophores and two monochlorotriazinic groups as reactive groups in their structure. The combined oxidation/reduction at 125 mA cm-2 in a filter-press cell without compartment separation was carried out using an anode of Ti/SnO2eSbePt and a cathode of stainless steel. This procedure has been effective in previous experiments using sulphate as electrolyte. A significant decrease in total organic carbon (TOC), chemical oxygen demand (COD), and total nitrogen (TN) was obtained. Moreover, the process took place efficiently. The average oxidation state (AOS) and the carbon oxidation state (COS) data confirmed the presence of stable oxidized intermediates in the electrolysed solution. The chromatography and the UVeVisible spectrophotometry assays indicated that full decolourisation is obtained at a loaded charge of around 0.81 Ah L-1 which is associated with an electrical energy per order (EEO) of 1.20 kWh m-3., The authors wish to thank the Spanish Agencia Estatal de Investigación (AEI) and European Union (FEDER funds) for the financial support (contract MAT2016-77742-C2-1-P and Red E3Tech CTQ2017-90659-REDT). The authors wish to acknowledge Tim Vickers for help with the English revision and Texcoy S.L. company (Spain) where the dyeing processes were done.

This study reports the bio-mediated synthesis of tungsten trioxide nanostructures from aqueous extracts of Melia azedarach (L.) dry leaves. The synthesis was carried out by electrochemical anodization of tungsten foils in the presence of different volume percentages of leaves extracts. These nanostructures were afterwards characterized by X-Ray Diffraction (XRD), impedance measurements and linear sweep voltammetry in 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 as anodes in Li-ion rechargeable batteries. Description of methods used for collection/generation of data: - Synthesis of WO3 nanostructures: The leaves of M. azedarach were randomly sampled from several mature trees from the surroundings of the Burjassot Campus of the University of Valencia (Spain). Fresh leaves were rinsed with tap and distilled water and subsequently air-dried indoors for 1 week, at room temperature. The extracts were obtained from dried leaves, by mixing 15 g of material with 150 mL of distilled water at 60 ºC. The infusion was maintained at that temperature for 20 min. After that, the solution, once cooled, was filtered through filter paper and used to prepare the different reaction media. Nanostructures of WO3 were synthesized by subjecting tungsten foils (1,3 cm2 of exposed area) to an anodization process with a cell potential of 20 V, for 4 h. A platinum foil served as the cathode within the cell. The anodization process employed an aqueous electrolyte composed of 1.5 M methanesulfonic acid (MSA) with varying proportions of M. azedarach leaves extract (from 0% to 10%, in volume), at a temperature of 50◦C. Anodization was performed under controlled hydrodynamic conditions, by means of a Rotating Disk Electrode (RDE) set a constant rotation speed of 750 rpm. Following anodization, a thermal treatment (annealing) was carried out in a tubular oven at 600◦C for 4 h in an air atmosphere to obtain crystalline WO3 nanostructures. - Morphological and structural characterization: X-Ray diffraction analyses (XRD) were performed to investigate the crystallinity of the WO3 samples. A D8AVANCE diffractometer (Bruker) equipped with a monochromatic Cu Kα1 source was used. -(Photo)electrochemical characterization: impedance measurements and photocurrent density vs potential curves: Electrochemical characterization of the WO3 nanostructures was conducted through impedance measurements, performing Electrochemical Impedance Spectroscopy (EIS) and Mott-Schottky (MS) analyses. All electrochemical tests were carried out using a three-electrode cell with the nanostructures acting as working electrodes, a silver/silver chloride (3 M KCl) electrode was the reference electrode and a platinum tip served as counterelectrode. Measurements were performed with a PalmSens4 potentiostat and 0.1 M H2SO4 was used as electrolyte. The sample area exposed to that electrolyte was 0.5 cm2. For EIS, a constant potential of 1 V was selected with an amplitude of 10 mV, scanning the frequency from 100 kHz to 10 mHz. For MS analysis, a constant frequency of 5 kHz was used, while the potential was scanned from 1 V to 0.2 V at a rate of 50 mV/s. For the photoelectrochemical characterization of the WO3 nanostructures, the same experimental set-up was used, with the addition of a solar simulator with AM 1.5 conditions (100 mW/cm2). Linear voltammetries to obtain photocurrent density – potential curves were conducted from 0.2 V to 1.05 V, by applying dark-light pulses (16 s in the dark followed by 4 s with illumination) while the potential was scanned. - Evaluation of WO3 nanostructures as Li-ion battery anodes: WO3 nanostructures were evaluated as anodes (negative electrodes) for Li-ion batteries. For that purpose, Swagelok-type cells were used, with WO3 nanostructures acting as working electrodes and a metallic lithium foil acting as both the counter and the reference electrodes. Batteries were assembled inside an Ar-filled glove box, using 1 M LiPF6 in ethylene carbonate/dimethyl carbonate/diethyl carbonate 1:1:1 (v/ v/v) as electrolyte (Sigma-Aldrich) and a Whatman glass microfiber separator. After sealing the cells, they were cycled outside the glove box at room temperature, using a Biologic BCS-815 cyclic station. Galvanostatic charge/discharge curves were recorded at different cycling rates (from C/10–1 C, and returning to C/10) within a potential window between 1 V and 3.5 V vs Li/Li+.

The dataset contains the data that have been obtained during the synthesis and the characterization (structural, compositional, and electrochemical) of TiO2/ZnO2 hybrid nanostructures used in photoelectrochemical applications. TiO2/ZnO hybrid nanostructures were synthetized by electrochemical anodization of titanium to form TiO2 nanosponges with crystalline structure and subsequently ZnO electrodeposition. Different Zn(NO3)2 concentrations were used for electrodeposition (10–60 mM). A structural and compositional characterisation was performed using X-Ray Diffraction (XRD). Electrochemical characterisation of nanostructures was performed by Photoelectrochemical Water Splitting (PWS), stability to photocorrosion, Electrochemical Impedance Spectroscopy (EIS), and Mott-Schottky tests.
