چکیده مقاله
Among different phases of MnO2, δ MnO2 is thought to be of special interest for electrochemical applications due to its large interlayer distance of ~7 Å Here, the reasonable loading of δ MnO2 catalyst at the cathode can consider as a vital factor influencing the performance of microbial fuel cells MFCs Therefore, the purpose of this study is to examine the efficiency of flower like δ MnO2 cathode catalyst loading for power generation in MFCs For this, a series of MFCs with δ MnO2 cathode catalyst at three different mass loadings 0 5, 1 and 1 5 mg/cm2 are performed The δ MnO2 catalyst characterize by X ray diffraction, scanning electron microscopy, Raman spectroscopy and Nitrogen adsorption desorption As a result, the MFCs with 1 mg δ MnO2/cm2 catalyst cathode generate more power 144±4 mW/m2 than those with 0 5 98±4 mW/cm2 and 1 5 131±6 mW/cm2 mg/cm2 δ MnO2 cathodes These MFCs offered somewhat 4 7% lower internal resistance than others Overall, the flower like δ MnO2 with 1 mg/cm2 at the cathode can be more efficient for power generation in MFCs
