Here details of collection methods and the analysis instrumentation are given. Also the raw data of hematite sample analysis and the data for photocurrent measurements and oxygen evolution data are provided. 2019-02-26 University of Bath public RightsHolder University of Bath Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/P008097/1 Nanostructured Metal Oxides for Solar Fuels Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/L016354/1 EPSRC Centre for Doctoral Training in Sustainable Chemical Technologies Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 PR16195 EPSRC National Facility for XPS (‘HarwellXPS’), operated by Cardiff University and UCL cent_sus_tech The techniques used were as follows: Electron Microscopy – SEM and TEM; X-ray diffraction – powder samples; Photoelectrochemistry – potentiostat and electrochemical cell linked to a calibrated solar simulator light source; X-ray photoelectron spectroscopy for surface analysis of element and oxidation states; UV-visible spectroscopy – analysis of organic compounds and bonding; Raman analysis – analysis of organic compounds and bonding; O2 evolution analysis – fluorescent probe. Powder samples were hand ground before mounting on sample holders for powder X-ray analysis, Raman and UV-visible spectroscopy. For TEM, samples were hand ground then briefly sonicated in propanol before a drop of the suspension was applied to formvar and carbon coated copper mesh grids. For all details see attached Data Collection Methods document and links to related publications. Hematite amples for SEM were prepared on electrically conductive ABS-FTO glass, gold sputter coating was therefore not required for SEM observation. Hematite samples for TEM were prepared by briefly sonicating a small amount of sample in propanol before one drop of the dilute suspension was places on carbon coated copper TEM grids. Hematite samples for XRD were prepared by hand grinding before placing in a powder sample holder disk and levelled. https://doi.org/10.1016/j.jpowsour.2018.10.007 https://doi.org/10.1039/C8SE00372F en 1 10.15125/BATH-00599 https://doi.org/10.1021/acsaem.8b02113 pub
