Iron oxide (Fe2O3), commonly known as hematite, is a naturally occurring ceramic semiconductor with significant structural rigidity and moderate ductility. It is widely used in pigments, catalysts, and magnetic applications across chemical processing, construction, and electronics industries, where its corrosion resistance, thermal stability, and abundance make it a cost-effective choice for high-temperature and corrosive environments. As a semiconductor, Fe2O3 is also gaining traction in photocatalysis and photoelectrochemical water splitting research, positioning it as a promising material for sustainable energy applications where its bandgap and electron transport properties offer advantages over competing oxides.
