报告摘要:

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 such as pigments, magnetic recording media, catalysis, and magnetic fluids. Iron oxides have shown potential in industrial, water purification, and photocatalytical trasnfromation to generate solar fuel. For example, ferrites have a molecular formula, M-Fe2O4 in which Fe2O3 is combined with a metal oxide (M-O) have demonstrated their roles in water purification and hydrogen and methane production under solar irradiance. More recently focus is also on the high-valent iron species, which have shown their involvement in numerous chemical, biological, and environmental reactions. In the past decade, there is an increasing interest in tetraoxy high-valent iron anions, commonly called ferrates (e.g. ferrate(VI), FeVIO42- and ferrate(V), FeVO43-) in aqueous solutions due to their importance in high energy density rechargeable batteries, in cleaner (“greener”) technology for organic syntheses, in environmentally friendly water and wastewater treatment processes. The presentation will focus on the fundamental chemistry of ferrites and ferrates, followed by examples to show their applications in the development of alternative energy for fuel and chemicals for purifying waters from toxins and micropollutants to meet major challenge for environmental sustainability.
