A facile nonpolar organic solution process of a
We present a facile nonpolar organic solution synthesis and processing method for water splitting photoanodes based on iron oxide with a relatively low sintering temperature (550 °C). The photocurrent of these photoanodes can reach 3.3 mA cm−2 at 1.23 V vs. RHE with high IPCE and stability, which makes them

Hematite - New World Encyclopedia
Hematite (American English) or haematite (British English) is a common mineral that is mined as the principal ore of iron. Chemically, it corresponds to iron(III) oxide (Fe2O3), one of several iron oxides. It can be found in a range of colors, including black, silver-gray, and brown to reddish brown.

Ultrafast Charge Carrier Recombination and Trapping in
Transient absorption spectroscopy on subpicosecond to second time scales is used to investigate photogenerated charge carrier recombination in Si-doped nanostructured hematite (α-Fe2O3) photoanodes as a function of applied bias. For unbiased hematite, this recombination exhibits a 50% decay time of ∼6 ps, ∼103 times faster than that of TiO2 under comparable conditions. Anodic bias ...
