Down the Profile

Hematite Photoanodes from the Iron Oxides of One Lateritic Pit, Horizon by Horizon

A paper from the School of Underlying Conditions digs one lateritic profile to 5.2 m, dissolves the iron oxides of each of its six described horizons without purifying them, and casts each extract into a hematite thin-film photoanode beside a reagent-salt control. Photocurrent at 1.23 V fell as the aluminium and silicon carried in with the iron rose, from ferricrete films that outperformed the control to pallid-zone films that were mostly not hematite, and two 5 cm transects found the films changing where the surveyor had drawn each boundary, abruptly across a clear one and over about 30 cm across a gradual one.
