Description

Contents of data folder: Electrochemical Data -> Electrochemical Data.xlsx Contains the electrochemical data obtained from IviumSoft used for Figures 3, 4, 5, 6, 7, 10, S5, S6, S7, S9, S13 and S17. Electrolysis GC Data -> Electrolyser GC Data.xlsx -> Electrolyser GC Data (Seawater).xlsx Contains integration data from Agilent GC software for H2 and O2 quantification and the calculations used to convert GC data into amounts of product. Elemental Abundance Price Data -> Elemental Cost-Abundance Data.xlsx Contains crustal abundance data of elements tabulated from P.A. Cox The Elements: Their Origin, Abundance, and Distribution and price data tabulated from the US Geological Survery Mineral Commodity Summaries. Used for Figure S1. Fe content UV-vis -> Fe content and calibration.xlsx Contains the UV-vis spectral data from Agilent software of absorption by Fe species dissolved in concentrated HCl. Both the calibration and spectra for the synthesised materials are shown. Also includes the calculation of converting UV-vis absorption to quantification of Fe content in electrodes. Used for Table S1 and Figure S14. SEM -> “Material Name” -> “as-prepared/HER/OER” .tiff Contains original SEM images as .tiff files for all the materials used in this work, as-prepared, after HER catalysis and after OER catalysis. Used for Figures 1, S8 and S16. XPS -> XPS_Raw_Data.vms -> XPS_C1s_Calibrated.vms -> XPS_Data_Fit.vms -> XPS Data File Information.rtf Contains the XPS raw data file from CasaXPS in original .vms along with the data calibrated to adventitious C1s and with peak fittings. The Data File Information contains further information about how to navigate the .vms files in CasaXPS. XPS -> Fe2p_Fit_TXT -> Raw_Data_TXT -> S2p_Fit_TXT Contains XPS raw data, Fe2p fit data and S2p fit data exported from CasaXPS as .txt files, used in Figures 2, 9, S3, S4, S10, S11 and S12. XRD -> XRD_Raw.xlsx Contains the raw XRD data from PANanalytical software used for Figures S2 and S15.
