Fe3O4 Nanoparticles Dispersed on Douglas Fir Biochar for Phosphate Sorption

Image of Fe3O4 Nanoparticles Dispersed on Douglas Fir Biochar for Phosphate Sorption

The recent work by Todd Mlsna group has been featured on the front cover of ACS Applied Nano Materials (June issue).

This graphic illustrates chemically coprecipitated magnetite (Fe3O4) nanoparticles (~16.7 nm diameter) dispersed on a high-surface-area (~695 m2/g) syn gas by product Douglas fir biochar. The prepared composite material performed approximately 20 times better than bare magnetite nanoparticles for sorptive removal of phosphate. The possible chemisorbed phosphate surface species bidentate (corner and edge sharing) and monodentate are displayed on the enlarged section. This study effectively demonstrated a strategy to combat the limitations (surface area, particle aggregation, pressure drop in columns, nanotoxicity, and commercialization difficulties) of using nano-iron oxides in commercial sorption applications.
