In this paper, we report a strategy to perform in-situ incorporation of oxygen evolution catalyst (OEC), Co3O4, during hydrothermal growth of Fe2O3 nanorod arrays. It was found that the highest photocurrent increase and onset potential shift was observed with 5% Co2+. The photocurrent density increa...
