Renewable biomass derived hierarchically porous carbonaceous sponges and their magnetic nanocomposites for removal of organic molecules from water

Hierarchically porous carbonaceous sponges and their magnetic nanocomposites were fabricated by a combined approach of hydrothermal carbonization and freeze drying. The resulting carbonaceous sponges have hierarchically porous structure and a large number of oxygen-containing functional groups. The unique structure enables carbonaceous sponges candidate materials for rapid and efficient organic molecules removal from water.
