“…The maximal power density of TNA‐NF was 157 mW m −2 (see Figure S4, Supporting Information), which was nearly 1.23 times higher than that of TNA‐HF (127 mW m −2 ). In the previous work, the maximum power density of the active carbon fiber felt was 33.5 ± 1.5 mW m −2 , and the maximum power density of graphite felt increased to 74.5 ± 7.5 mW m −2 , which is not comparable to the TNA‐based electrode in this work . Due to the differences in their morphologies/dimensions and spectroscopic characterizations, the TNA‐NF and TNA‐HF revealed the different production capacity.…”

To enhance the microbial fuel cell (MFC) for wastewater treatment and chemical oxygen demand degradation, TiO 2 nanotubes arrays (TNA) are successfully synthesized on Ti foil substrate by the anodization process in HF and NH 4 F solution, respectively (hereafter, denoted as TNA‐HF and TNA‐NF). The differences between the two kinds of TNA are revealed based on their morphologies and spectroscopic characterizations. It should be highlighted that 3D TNA‐NF with an appropriate dimension can make a positive contribution to the high photocatalytic activity. In comparison with the TNA‐HF, the 3D TNA‐NF sample exhibits a significant enhancement in current generation as the MFC anode. In particular, the TNA‐NF performs nearly 1.23 times higher than the TNA‐HF, and near twofold higher than the carbon felt. It is found that the two kinds of TiO 2 ‐based anodes have different conductivities and corrosion potentials, which are responsible for the difference in their current generation performances. Based on the experimental results, excellent stability, reliability, and low cost, TNA‐NF can be considered a promising and scalable MFC bioanode material.

“…Most recent evidence indicates that the disposal costs of sludge account for 25–60% of the total cost of wastewater treatment plant, excluding the costs of removing inorganic/organic pollutants5. Meanwhile, the highly concentrated organic matter in dredged sediments is also a risk for further ecological stabilization and additional utilization6. Bioremediation in comparison with the costly and highly risky physical and chemical remediation processes, is a green and cost-effective technology which also can be commercially utilized in large scale7.…”

A benthic microbial electrochemical systems (BMES) of 195 L (120 cm long, 25 cm wide and 65 cm height) was constructed for sediment organic removal. Sediment from a natural river (Ashi River) was used as test sediments in the present research. Three-dimensional anode (Tri-DSA) with honeycomb structure composed of carbon cloth and supporting skeleton was employed in this research for the first time. The results demonstrated that BMES performed good in organic-matter degradation and energy generation from sediment and could be considered for river sediments in situ restoration as novel method. Community analysis from the soil and anode using 16S rDNA gene sequencing showed that more electrogenic functional bacteria was accumulated in anode area when circuit connected than control system.

BACKGROUND Microbial electrosynthesis (MES) is a biocathode‐driven process, producing high‐value chemicals, from CO2. However, the low efficiency of the biocathode hinders the MES process efficiency significantly. RESULTS A novel 3D graphene–nickel foam (G‐NF) cathode has been fabricated, by hydrothermal approach for the improvement of microbially‐catalyzed reduction at the MES cathode. An increase of 1.8 times in the volumetric acetate production rate was obtained, compared with the untreated nickel foam. In MES with G‐NF, a volumetric acetate production rate of 3.11 mmol L‐1 day‐1 has been achieved; 70% of the electrons consumed were recovered and the final acetate concentration reached 5.46 g L‐1 within 28 days. CONCLUSION The hierarchical porous G‐NF cathode improved bacterial colonization and the efficiency of mass, nutrients and protons transfer due to its 3D composition; the graphene coating considerably increased the effective surface area for microbial adhesion, as well as the electron transfer rate of biofilm in the MES. This study attempted to improve the efficiency of the biocathode, and provides a promising large electrode for large‐scale MES devices. © 2017 Society of Chemical Industry
