Abstract

original image

Strong enhancing effect of plasmonic Au nanoparticles on the photoelectrochemical performance of a ZnFe2O4/ZnO heterojunction used as photoanode for water splitting application is demonstrated. The material properties of Au/ZnFe2O4/ZnO complement each other remarkably well in the configuration proposed in terms of their optical, electronic, and catalytic properties.
