Development of conductive carbon cathode catalyst from waste wood may provide an efficient and stable system of energy supply and contribute to countermeasures for global warming.
As nitrogen doping of carbon materials has been recognized as a potential method to enhance electro catalytic activity, we investigated the effect of sintering on the carbonization treatment of Sugi (Cryptomeria japonica) wood char. This study attempted to fabricate a catalytic cathode conductive carbon composite material of wood using non-platinum-carbon from nitrogen-doped wood.
Sugi wood char was, first carbonized in an electric furnace under nitrogen. Then the carbonized wood was sintered under nitrogen in a pulsed current apparatus.
The porous texture of carbonized Sugi wood char particles relative to material A weight percentages was investigated with scanning electron microscope. The texture of each carbonized wood particle had a jagged shape [See figure].
Optimal parameters for the precarbonization treatment and sintering process were applied to improve the electrochemical performance of the fuel cells.
