Description The effect of coconut shell biochar on dye degradation in a microbial fuel cell (MFC) was investigated in the
present study. Two different doses of biochar (0.5 g and 1 g) and one control without bio-char were studied. The
highest COD removal efficiency was about 77.7% (0.5 g biochar), maximum current (1.07 mA) and voltage
(722 mV) were obtained with 1 g biochar. Biofilm optical microscopy characterization revealed the micro colonies
intricate plate-like structures. High adsorbent dosage might provide a high surface area for biofilm to
generate electricity. BET results of coconut shell biochar showed the maximum surface area of 0.9669m2/g and
macroporosity (0.0032 cm3/g). The overall results highlighted the possibility of using biochar as an additive in
MFC for efficient dye degradation.
