Mesoporous 2-Line Ferrihydrite by a Solution-Phase Cooperative Assembly Process for Removal of Organic Contaminants in Air

摘要

Iron for cleaner air: 2-Line ferrihydrite, a versatile iron material, has been successfully explored for air purification by preparing it in a partially dehydroxylated form with accessible mesopores. The readily exposed tri- and tetracoordinated surface iron sites with numerous electrophilic oxygen species make this environmentally friendly material the most efficient iron candidate for complete elimination of organic contaminants in air.
