title: Highly-oriented Fe2O3/ZnFe2O4 nanocolumnar heterojunction with improved charge separation for photoelectrochemical water oxidation.
abstract: This paper describes the design and synthesis of a heterojunction photoanode composed of highly-oriented Fe2O3/ZnFe2O4 nanocolumnar arrays with a well-defined morphology by reactive ballistic deposition and atomic layer deposition. This specific structure enhances the charge separation at the Fe2O3/ZnFe2O4 interface, leading to an improved photoelectrochemical performance for water oxidation.
