A versatile biomass derived carbon material for oxygen reduction reaction, supercapacitors and oil/water separation

This study describes the synthesis of functional carbons from poplar catkin via multiple channels. Nitrogen and oxygen dual-doped carbon delivers excellent electrochemical characteristics for oxygen reduction reaction and supercapacitors. Oleophylic carbon aerogel is proven to be superoleophilic and highly porous enough to “wet” with oils and organic liquids and repel water completely to achieve oil/water separation.262
