Enhanced photoelectrochemical activity of nanostructured ZnFe2O4 thin films prepared by the electrospray technique

Abstract

Nanostructured spinel zinc ferrite (ZnFe₂O₄) thin films were prepared, using the electrospray technique, as photoabsorber material for photoelectrochemical water splitting. An enhanced photocurrent of 53 μA cm⁻² at 1.23 V versus RHE was achieved, which is among the best results obtained for unmodified ZnFe₂O₄ photoanodes.
