Synthesis of a single-crystal Fe(2)O(3) nanowire array based on stress-induced atomic diffusion used for solar water splitting

In this study, we successfully fabricated a single-crystal Fe(2)O(3) nanowire array based on stress-induced atomic diffusion and used this array as the photoelectrode for solar water splitting. With the surface polishing treatment on the sample surface, the density of the Fe(2)O(3) nanowire array re...

description In this study, we successfully fabricated a single-crystal Fe(2)O(3) nanowire array based on stress-induced atomic diffusion and used this array as the photoelectrode for solar water splitting. With the surface polishing treatment on the sample surface, the density of the Fe(2)O(3) nanowire array reached up to 28.75 wire µm(−2) when heated for 90 min at 600°C. The photocurrent density of the optimized sample was 0.9 mA cm(−2) at 1.23 V versus a reversible hydrogen electrode in a three-electrode system under AM 1.5 G illumination. The incident photon-to-electron conversion efficiency was 6.8% at 400 nm.
