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].

Photo-production of reactive oxygen species and ...

The geochemical cycling of iron and carbon can couple in unique ways in the euphotic zone of aquatic systems. For example, the prevalence of hematite nanoparticles and low molecular weight organics that can functionalize their surfaces, such as oxalate, creates a solar-photoactive interfacial system capable of generating reactive oxygen species (ROS) that degrade natural organic matter.
