Abstract

Here we show that hematite (\textgreeka-Fe2O3) nanostructures with a high water splitting performance can be formed on Fe--Ti alloys using the most simple thermal treatment in air and Ar. The use of the Fe--Ti alloy suppresses the formation of thick suboxide underlayers that are strongly detrimental for the photoconversion efficiency. The formed nanorod structures show an onset potential of up to 0.6--0.7 VRHE. This beneficial effect is attributed to the combination of suppression of a thick suboxide and the nature of the \textgreeka-Fe2O3 nanorods after Ar annealing.
