“…The detection of many analytes (N 2 O, , NO 2 – , NO 3 – , CO 2 , hydrazine, organic carbon content, and so on) is hindered by the presence of oxygen in the solution. A common method to eliminate dissolved oxygen in laboratory experiments is the purge of the solution with an inert gas such as nitrogen or argon.…”

“…Porous silver electrodes were initially used to remove oxygen in the solution of analysis . Different configurations and electrode materials have been proposed to reach the complete oxygen removal for analytical or other purposes. ,− Drawbacks of such approaches are the production of H 2 O 2 or the alteration of pH due to a quantitative conversion of oxygen initially present in the treated solution . Miniaturization has been described using two gold porous electrodes in a glass microcapillary to remove oxygen interfering with N 2 O detection, and application of electrochemically dissolved oxygen removal from microfluidic streams was also shown .…”

“…Premier et al proposed that a carbon‐electrode‐based MFC, carbon paper as the anode and carbon paper/Pt as the cathode, can be used as a biosensor for specific recognition of volatile fatty acids . Researchers have also investigated micro‐MFC‐based biosensor devices for the detection of heavy‐metal ions, toxic substances, organic carbon species, and microbial activity …”

Microbial fuel cells (MFCs) have attracted considerable interest due to their potential in renewable electrical power generation using the broad diversity of biomass and organic substrates. However, the difficulties in achieving high power densities and commercially affordable electrode materials have limited their industrial applications to date. Carbon materials, which can exhibit a wide range of different morphologies and structures, usually possess physiological activity to interact with microorganisms and are therefore fast-emerging electrode materials. As the anode, carbon materials can significantly promote interfacial microbial colonization and accelerate the formation of extracellular biofilms, which eventually promotes the electrical power density by providing a conductive microenvironment for extracellular electron transfer. As the cathode, carbon-based materials can function as catalysts for the oxygen-reduction reaction, showing satisfying activities and efficiencies nowadays even reaching the performance of Pt catalysts. Here, first, recent advancements on the design of carbon materials for anodes in MFCs are summarized, and the influence of structure and surface functionalization of different types of carbon materials on microorganism immobilization and electrochemical performance is elucidated. Then, synthetic strategies and structures of typical carbon-based cathodes in MFCs are briefly presented. Furthermore, future applications of carbon-electrode-based MFC devices in the energy, environmental, and biological fields are discussed, and the emerging challenges in transferring them from laboratory to industrial scale are described.

“…The DO could act as an additional competitive electron acceptor for the bioanode sensing element, thus decrease the electric signal output of MFC sensor. In practice, additional respiratory inhibitor, e.g., azide, or deoxidation preprocessing is required to obtain higher sensitivity when the DO of the water sample exceeded certain limits (Chang et al, 2005;Quek et al, 2015). However, the addition of inhibitor is strictly limited because of the potential environmental leakage.…”

The traditional microbial fuel cell (MFC) sensor with bioanode as sensing element delivers limited sensitivity to toxicity monitoring, restricted application to only anaerobic and organic rich water body, and increased potential fault warning to the combined shock of organic matter/toxicity. In this study, the biocathode for oxygen reduction reaction was employed for the first time as the sensing element in MFC sensor for toxicity monitoring. The results shown that the sensitivity of MFC sensor with biocathode sensing element (7.4±2.0 to 67.5±4.0mA%cm) was much greater than that showed by bioanode sensing element (3.4±1.5 to 5.5±0.7mA%cm). The biocathode sensing element achieved the lowest detection limit reported to date using MFC sensor for formaldehyde detection (0.0005%), while the bioanode was more applicable for higher concentration (>0.0025%). There was a quicker response of biocathode sensing element with the increase of conductivity and dissolved oxygen (DO). The biocathode sensing element made the MFC sensor directly applied to clean water body monitoring, e.g., drinking water and reclaimed water, without the amending of background organic matter, and it also decreased the warning failure when challenged by a combined shock of organic matter/toxicity.
