Ferrites and Ferrates: Chemistry and Applications in Sustainable Energy and Environmental Remediation (#13)

Iron and its oxides are not only greener than many of precious known metals, but can perform numerous catalytical reactions of industrial and environmental interests. For examples, iron oxides have shown their potentials in pigments, magnetic recording media, magnetic fluids, water purification, and photocatalytical transformation to generate solar fuel. For example, ferrites, with a molecular formula, M-Fe2O4 in which Fe2O3 is combined with a metal oxide (M-O), have demonstrated their roles in purifying water and in generating hydrogen and methane under solar irradiance. In recent years, there is renewed interest in high-valent iron species (e.g. ferrate(VI), FeVIO42- and ferrate(V), FeVO43-), which have potentials in numerous energy and remediation applications. The symposium will focus on the synthesis and characterization of ferrites and ferrates and their fundamental chemistry. Symposium will draw examples of applications of environmentally benign ferrites and ferrates, which include development of alternative energy for fuel (e.g. CO2 transformation and reduction and water splitting for hydrogen production) and purifying waters from toxic metals (e.g. arsenic), emerging contaminants (e.g. nitrosamines, antibiotics, and estrogens), microorganisms (e.g. Bacteriophage MS2, Escherichia coli), and toxins (e.g. microcystins) to meet major challenges for environmental sustainability.
