This study summarizes the recent progress of alpha-Fe2O3 nanostructured thin films in improving water oxidation. Strategic modifications of alpha-Fe2O3 photoanodes including nanostructuring, heterojunctions, surface treatment, elemental doping, and nanocomposites are highlighted and discussed. Prospects related to the challenges and research in this innovative research area are provided as a guiding layout for improving alpha-Fe2O3 photoanodes in photoelectrochemical water oxidation.
Solar-assisted water splitting using photoelectrochemical (PEC) cell is an environmentally benign technology for the generation of hydrogen fuel. However, several limitations of the materials used in fabrication of PEC cell have considerably hindered its efficiency. Extensive efforts have been made to enhance the efficiency and reduce the hydrogen generation cost using PEC cells. Photoelectrodes that are stable, efficient and made of cost-effective materials with simple synthesizing methods are essential for commercially viable solar water splitting through PEC technology. To this end, hematite (alpha-Fe2O3) has been explored as an excellent photoanode material to be used in the application of PEC water oxidation owing to its suitable bandgap of 2.1 eV that can utilize almost 40% of the visible light. In this study, we have summarized the recent progress of alpha-Fe2O3 nanostructured thin films for improving the water oxidation. Strategic modifications of alpha-Fe2O3 photoanodes comprising nanostructuring, heterojunctions, surface treatment, elemental doping, and nanocomposites are highlighted and discussed. Some prospects related to the challenges and research in this innovative research area are also provided as a guiding layout in building design principles for the improvement of alpha-Fe2O3 photoanodes in photoelectrochemical water oxidation to solve the increasing environmental issues and energy crises.
