Cobalt-doped double-layer α-Fe₂O₃ nanorod arrays for enhanced photoelectrochemical reduction of Cr(VI).

ABSTRACT: Element doping is an important method for improving the performance levels of photoelectrochemical (PEC) cells. Nevertheless, to date, the PEC conversion efficiency and photocurrent characteristics of the available photoanodes remain very low. In this study, cobalt (Co) was selectively doped into the bottom and/or top layers of double-layered α-Fe₂O₃ nanorod arrays grown on conductive transparent substrates (F:SnO₂, FTO) via a two-step hydrothermal method; this process was performed to enhance the charge transfer ability and thus significantly improve the PEC performance. The light response capabilities of all α-Fe₂O₃ films were evaluated by an electrochemical workstation under dark or visible light irradiation conditions. The sample o
