Diethylenetriamine-assisted hydrothermal synthesis of dodecahedral alpha-Fe2O3 nanocrystals with enhanced and stable photoelectrochemical activity

摘要

Dodecahedral alpha-Fe2O3 nanocrystals (D-hematite) were successfully synthesized through a hydrothermal method involving FeS-diethylenetriamine (FeS-DETA) hybrid nanosheets as starting materials. The photoanode made by assembling the as-obtained D-hematite on ITO substrates exhibited efficient photoelectrocatalytic water splitting activity and good stability in 1.0 M KOH aqueous solution under visible light irradiation.
