Funding Information:
Muhammad Usman is an Alexander von Humboldt postdoctoral fellow with Stefan Haderlein at the University of Tübingen, Germany. He also holds the position of an Assistant Professor in the Institute of Soil and Environmental Sciences at the University of Agriculture, Faisalabad, Pakistan. He obtained his B.S. in Soil Science at the latter organization. He was, then, awarded a fellowship from Higher Education Commission of Pakistan to pursue further studies from France. He obtained his M.S. (2008) in environmental sciences from AgroParisTech and Ph.D. (2011) in iron geochemistry and environmental remediation from University of Lorraine under the supervision of Christian Ruby, Khalil Hanna, and Pierre Faure. His research concerns iron-mediated remediation of soil and water contaminants. Major focus of his research is the synthesis and use of mixed-valent iron minerals for environmental remediation with an emphasis on advanced oxidation processes (Fenton and persulfate oxidation) and sorption.

N2 - Mixed-valent iron [Fe(II)-Fe(III)] minerals such as magnetite and green rust have received a significant amount of attention over recent decades, especially in the environmental sciences. These mineral phases are intrinsic and essential parts of biogeochemical cycling of metals and organic carbon and play an important role regarding the mobility, toxicity, and redox transformation of organic and inorganic pollutants. The formation pathways, mineral properties, and applications of magnetite and green rust are currently active areas of research in geochemistry, environmental mineralogy, geomicrobiology, material sciences, environmental engineering, and environmental remediation. These aspects ultimately dictate the reactivity of magnetite and green rust in the environment, which has important consequences for the application of these mineral phases, for example in remediation strategies. In this review we discuss the properties, occurrence, formation by biotic as well as abiotic pathways, characterization techniques, and environmental applications of magnetite and green rust in the environment. The aim is to present a detailed overview of the key aspects related to these mineral phases which can be used as an important resource for researchers working in a diverse range of fields dealing with mixed-valent iron minerals.
