报告简介：

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 and iron oxide-based compounds such as ferrite (Fe^IIIO₂^-, Fe^III₂O₄^2-) and ferrate (Fe^VIO₄^2-) are used in a wide range of applications such as pigments, magnetic recording media, catalysis, magnetic fluids, energy transformation under solar irradiance, and water purifications.  Performance of iron oxides can be enhanced by combining with noble metals (e.g. Ag). Carbon-based materials like graphene with large surface area result in three-dimensional nanostructures, which have unique adsorption properties to clean the environment.  The presentation gives fabrication and characterization of environmentally benign materials.  Applications will focus on multifunctional properties of earth abundant, iron-based materials/composites that can address challenging demands of sustaining the energy demand and the water supply in coming decades.
