“…The value of hematite cathode was close to recent studies of different type of catalysts. The maximum power of Co-naphthalocyanine (CoNPc/C) was 64.7 mW·m −2 at 0.25 mA as compared with 81.3 mW·m −2 of Pt/C, 29.7 mW·m −2 of NPc/C, and 9.3 mW·m −2 of carbon black when the cathodes were implemented in H-type MFCs [13]. In addition, the maximum power density of plain carbon paper was 67 mW·m −2 , 77 mW·m −2 for carbon felt, and 124 mW·m −2 (with Pt for 0.2 mg·cm −2 ) for platinum-coated carbon paper [5].…”

“…Promising results in terms of oxygen reduction reaction activity were non-precious metals linked with organics N 4 -chelating ligands and their polymeric derivatives [7][8][9][10], such as metals tetramethoxyphenylporphyrin (TMPP), CoTMPP, FeCoTMPP, ClFeTMPP, and metals phthalocyanine (Pc), FePc, CoPc, CoNPc, FeCuPc, etc. [11][12][13][14][15][16][17]. Although these catalysts have excellent performance, all of these materials should be prepared at a high temperature with inert atmosphere [8,[11][12][13], which makes the preparation more complicated and requires an extra cost.…”

Abstract:Developing cheap electrocatalysts for cathodic oxygen reduction in neutral medium is a key factor for practical applications of microbial fuel cells (MFCs). Natural hematite was investigated as a low-cost cathode to improve the performance of microbial fuel cells (MFCs). With hematite-coated cathode, the cell current density stabilized at 330.66 ± 3.1 mA·m −2 (with a 1000 Ω load) over 10 days under near-neutral conditions. The maximum power density of MFC with hematite cathode reached to 144.4 ± 7.5 mW·m −2 , which was 2.2 times that of with graphite cathode (64.8 ± 5.2 mW·m −2 ). X-ray diffraction (XRD), Raman, electrode potential analysis, and cyclic voltammetry (CV) revealed that hematite maintained the electrode activities due to the stable existence of Fe(II)/Fe(III) in mineral structure. Electrochemical impedance spectroscopy (EIS) results indicated that the cathodic electron transfer dynamics was significantly improved by using hematite to lower the cathodic overpotential. Therefore, this low-cost and earth-abundant natural mineral is promised as an effective cathode material with potential large-field applications of MFCs in future.

“…Although the improved power density was lower than expensive catalysts, the value of pyrrhotite cathode was close to some recent studies of MFCs with different type of catalysts. For example, the maximum power of 64.7 mW·m −2 for Co-naphthalocyanine, 81.3 mW·m −2 for Pt/C electrode, 29.7 mW·m −2 for NPc/C, and 9.3 mW·m −2 for carbon black in H-type MFCs [33]. Moreover, the value of pyrrhotite-coated cathode had similar values with hematite or manganese oxides (30-180 mW·m −2 ), carbon felt (77 mW·m −2 ) or PbO 2 (<80 mW· m −2 ) [21][22][23][24][25].…”

Abstract:Here we reported the investigation of enhanced performance for the removal of hexavalent chromium (Cr (VI)) by a new microbial fuel cell (MFC) with natural pyrrhotite-coated cathode. By comparisons of the graphite-cathode, the MFCs equipped with a pyrrhotite-coated cathode generated the maximum power density of 45.4 mW·m −2 that was 1.3 times higher than that of with bare graphite cathode (35.5 mW·m −2 ). Moreover, the Cr (VI) removal efficiency of 97.5% achieved after 4.5 h compared with only 46.1% by graphite cathode MFC. In addition, Cr (VI) removal rate with different initial Cr (VI) concentrations for 10 mg/L and 30 mg/L was investigated and a decreased removal percentage with increasing Cr (VI) concentration was observed. Batches of experiments of different pH values from 3.0 to 9.0 in catholyte were carried out to optimize system performance. The complete Cr (VI) removal was achieved at pH 3.0 and 99.59% of Cr (VI) was removed after 10.5 h, which met the requirement of the Cr (VI) National Emission Standard. When the value of pH was decreasing, the removal rate was obviously increased and Cr (VI) could be removed successfully with a broad pH range indicating pyrrhotite-coated cathode MFC had more extensive usage scope. Furthermore, cathode treatment products were studied by X-ray photoelectron spectroscopy (XPS), Cr 2 O 3 , Cr (III)-acetate were detected on the cathode by the XPS Cr2p spectra and no Cr (VI) founded, indicating that the Cr on the surface of cathode was Cr (III) and Cr (VI) were reduced. On cathode, pyrrhotite not only played a significant role for catalyst of MFCs, but also acted as reactive sites for Cr (VI) reduction. Our research demonstrated that pyrrhotite, an earth-abundant and low-cost natural mineral was promised as an effective cathode material. Which had great potential applications in MFCs for reduction of wastewater containing heavy metals and other environmental contaminants in the future.

“…Materials thus far studied as non-platinum catalysts in MFCs include cobalt tetramethylphenylporphyrin [1][2][3], manganese dioxide [4][5][6], co-naphthalocyanine [7], activated carbon [8,9], phosphorus-doped carbon [10,11], and so forth. However, none of them was proven good enough for practical use in terms of the productivity of electricity or durability over long hours of operation.…”

The potential of the use of zirconium, an abundant and less expensive element, as a non-platinum catalyst of the cathode in microbial fuel cells (MFCs) was studied. The oxygen reduction reaction (ORR) activity of various cathodes made from three kinds of zirconium-based materials (ZrO 2 , ZrCN, and ZrCNO) was evaluated under the operating conditions of MFC. Only ZrCNO catalyst exhibited ORR. Manipulation of parameters of the preparation conditions of the ZrCNO cathode (proportion of Ketjenblack, amount of Nafion, and coating amount of catalyst ink) improved the ORR activity about seven-to twenty-twofold, which was equivalent to about 26 − 29% of the activity of a platinum cathode. The ZrCNO cathode having the highest ORR activity was built into a MFC, which was then used in treating synthetic wastewater. The maximum current density attained was 0.58 W/m 2 , which is more than two fifths of the density achieved by a platinum cathode. Stable current density maintained by the MFC over about four weeks has made ZrCNO a promising non-platinum material for a cathode catalyst of MFCs.
