“… 38 Among the transition metal oxides, manganese oxide, particularly, Mn 3 O 4 , has gained limelight because of its high specific capacitance, outstanding structural flexibility, abundant nature, low cost, and environmental benignity. 39 Wang et al reported that Mn 3 O 4 nanoparticles synthesized through an ultrasound-assisted method exhibited a specific capacitance of 261 F/g at 0.4 A/g. 40 In the work reported by Qiao et al, porous Mn 3 O 4 synthesized via a solvothermal technique exhibited a specific capacitance of 302 F/g at 0.5 A/g with a capacitance retention of 89% even after 5000 cycles.…”

MXenes are the class of two-dimensional transition metal carbides and nitrides that exhibit unique properties and are used in a multitude of applications such as biosensors, water purification, electromagnetic interference shielding, electrocatalysis, supercapacitors, and so forth. Carbide-based MXenes are being widely explored, whereas investigations on nitride-based ones are seldom. Among the nitride-based MXenes obtained from their MAX phases, only Ti 4 N 3 and Ti 2 N are reported so far. Herein, we report a novel synthesis of V 2 NT x (T x is the surface termination) obtained by the selective removal of “Al” from V 2 AlN by immersing powders of V 2 AlN in the LiF–HCl mixture (salt–acid etching) followed by sonication to obtain V 2 NT x (T x = −F, −O) MXene which is then delaminated using the dimethyl sulfoxide solvent. The V 2 NT x MXene is characterized by X-ray diffraction studies, field emission scanning electron microscope imaging, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and high-resolution transmission electron microscope imaging. Supercapacitor electrodes are prepared using V 2 NT x MXenes and their electrochemical performances are examined by cyclic voltammetry, galvanostatic charge/discharge measurement, and electrochemical impedance spectroscopy. The V 2 NT x MXene electrode exhibits a specific capacitance of 112.8 F/g at a current density of 1.85 mA/cm 2 with an energy and power density of 15.66 W h/kg and 3748.4 W/kg, respectively, in 3.5 M KOH aqueous electrolyte. The electrode exhibits an excellent capacitance retention of 96% even after 10,000 charge/discharge cycles. An asymmetric supercapacitor fabricated with V 2 NT x as a negative electrode and Mn 3 O 4 nanowalls as a positive electrode helps obtain a cell voltage of 1.8 V in aqueous KOH electrolyte.

“…The power generated by MFCs depends on various factors such as the electron transfer rate from the bacteria to anode, the diffusion of substrate into the biofilm, the ohmic resistance of the electrolyte and the electrochemical kinetics. The maximum power generated by the MFC also depends on the total internal resistance of the system [ 99 , 100 ]. The reviews of the basic MFCs technology, challenges and applications can be found in several articles [ 101 , 102 ].…”

Microbial electrochemical systems are a fast emerging technology that use microorganisms to harvest the chemical energy from bioorganic materials to produce electrical power. Due to their flexibility and the wide variety of materials that can be used as a source, these devices show promise for applications in many fields including energy, environment and sensing. Microbial electrochemical systems rely on the integration of microbial cells, bioelectrochemistry, material science and electrochemical technologies to achieve effective conversion of the chemical energy stored in organic materials into electrical power. Therefore, the interaction between microorganisms and electrodes and their operation at physiological important potentials are critical for their development. This article provides an overview of the principles and applications of microbial electrochemical systems, their development status and potential for implementation in the biosensing field. It also provides a discussion of the recent developments in the selection of electrode materials to improve electron transfer using nanomaterials along with challenges for achieving practical implementation, and examples of applications in the biosensing field.

“…Therefore, the way to produce renewable energy from organic effluents and green treatments of liquid wastes has received much attention in MFC [2]. The device is able to produce renewable bioelectricity from stored chemicals found on organic pollutants in the presence of electroactive microorganisms (EAM) [3,4]. But the low power output, poor stability, and cost-ineffectiveness to upgrade the device are the main drawbacks that affect MFC [2].…”

“…To reduce these challenges, researchers have used transition metal oxide-(TMO-) based nanomaterial catalysts to modify such conventional carbon electrodes due to their low cost, environmentally friendly nature, abundance, high surface area to volume ratio, and fast electrokinetic activity in a widespread of electrochemical applications [7]. However, due to their poor electrical conductivity, poor dispersibility, and low stability in highly protonic media, they reduce their long-term electrocatalytic activity in bioenergy production (i.e., reduces the life cycle), bioremediation, and sensing activity [3,7]. Improving the electrochemical properties of TMO by forming a composite with conducting polymers enables to increase the life cycle of the modified electrode by improving its cycle stability in any energy conversion and storage applications.…”

In this study, biosynthesized α-MnO2/NiO NPs and chemically oxidative polyaniline (PANI) were synthesized to form ternary composite anode material for MFC. The synthesized materials were characterized with different materials (UV-Vis, FTIR, XRD, TGA-DTA-DSC, SEM-EDX-Gwyddion, CV, and EIS) to deeply examine their optical, structural, morphological, thermal, roughness, and electrocatalytic properties. The degree of surface roughness for α-MnO2/NiO/PANI was 23.65 ± 5.652 nm . This value was higher than the pure α-MnO2, pure PANI, and even α-MnO2/PANI nanocomposite due to surface modification. The total charge storing performance for bare PGE, α-MnO2/PGE, PANI/PGE, α-MnO2/PANI/PGE, and α-MnO2/NiO/PANI/PGE were 5.291, 17.267, 20.659, 23.258, and 24.456 mC. From this, the charge storing performance formed by α-MnO2/NiO/PANI-modified PGE was highest, indicating that this electrode is best in cycle stability and increases its life cycle during energy conversion time in MFC. This is also supported by its effective surface area, having a value of 0.00984 cm2. From this, it is evidenced that the ternary composite catalyst-modified anode facilitates the fast electrocatalytic activity as observed from its high peak current and lower peak-to-peak potential separation ( Δ E p = 0.216 V ) than other electrodes. Such surface modification helps to store more electrical charge by increasing electrical conductivity during its charge/discharge processing time. In addition, the lower charge transfer resistance property with a value of 788.9 Ω and the fast heterogeneous electron transfer rate of ~2.92 s-1 enable to facilitate glucose oxidation, and this enhances to produce high power output and increase wastewater treatment efficiency. As a result, the bioelectrical activity of α-MnO2/NiO/PANI composite-modified PGE was very effective in producing a maximum power density of 506.96 mW m-2 with COD of 81.92%. The above observations justified that α-MnO2/NiO/PANI/PGE serves as an effective anode material in double-chambered MFC application.
