Near-field plasmonic functionalization of light harvesting oxide-oxide heterojunctions for efficient solar photoelectrochemical water splitting: The AuNP/ZnFe2O4/ZnO system

摘要

Strong enhancing effect of plasmonic Au nanoparticles on the photoelectrochemical performance of a ZnFe_2O_4/ZnO heterojunction used as photoanode for water splitting application is demonstrated. The material properties of Au/ZnFe_2O_4/ZnO complement each other remarkably well in the configuration proposed in terms of their optical, electronic, and catalytic properties.
