Hematite an overview ScienceDirect Topics

Advantages of Hematite. Hematite has been extensively studied as a promising photoanode because of its good light-harvesting ability, stability in aqueous environments, abundance in nature, and environmentally benign characteristics. It absorbs in the near-infrared region, and exhibits a band gap energy of 1.9–2.2 eV, depending on the synthesis method employed [14].
