Comparative Electricity Generation by Two Locally Produced Corncob Pyrochar Electrodes and Graphite using Microbial Fuel Cell Technology

The raw data presented here are the results obtained during the study on
comparative electricity generation by two locally produced corncob
pyrochar electrodes and graphite using microbial fuel cell technology.
The potential application of the electrode materials produced from corncobs through
pyrolysis and activation (in a seperate experiment) was tested along
with graphite (for reference) in dual-chambered microbial fuel cells (MFC)
using wastewater from Hydrothermal Carbonization (HTC) and Biogas
Digestate (BD) as substrates. It was concluded that, MFC operated with KOH-activated corncob pyrochar electrode
(KAC) which had the largest BET surface area (1626 m2/g) and porosity using biogas digestate performed best
with a power output of 316.8 µW and Coulombic Efficiency of 75% compared to 64% and 48% of the steam-activated corncob pyrochar electrode (SAC) and graphite eelctrode respectively.

本数据集收录的原始数据，来自一项针对两种本地制备的玉米芯热解炭（corncob pyrochar）电极与石墨电极的微生物发电性能对比研究，实验采用微生物燃料电池（microbial fuel cell, MFC）技术开展。研究团队先通过热解与活化（于独立实验中完成）制备了玉米芯基电极材料，并将其与作为参比的石墨电极，共同搭载于双室微生物燃料电池（MFC）中，以水热碳化（hydrothermal carbonization, HTC）废液与沼气消化液（biogas digestate, BD）作为底物进行性能测试。研究结论显示，搭载氢氧化钾活化玉米芯热解炭（KOH-activated corncob pyrochar, KAC）电极的微生物燃料电池表现最佳：该电极拥有最大的BET比表面积（BET surface area，1626 m²/g）与孔隙率，当以沼气消化液为底物时，其最大功率输出为316.8 μW，库仑效率达75%；而水蒸气活化玉米芯热解炭（steam-activated corncob pyrochar, SAC）电极与石墨电极的库仑效率分别为64%与48%。
