Sn-doped hematite films as photoanodes for efficient photoelectrochemical water oxidation†
Abstract
Sn-doped hematite films were electrochemically deposited on a fluorine-doped tin oxide substrate for use as an anode for photoelectrochemical water oxidation. A high photocurrent of ∼2.8 mA cm−2 at 1.24 V vs. RHE and a conversion efficiency of 0.24% are achieved.
