A biobased polyelectrolyte was prepared and used successfully as a precursor for the fabrication of N-doped hierarchically porous carbon materials with tunable electrochemical properties in supercapacitors.
A novel Fe3O4/C composite with a hierarchical pore carbon network has been synthesized simply by one-step pyrolysis synthesis using ferrous gluconate as the precursor, which shows excellent electrochemical properties as an anode material for LIBs.
