“…The photo-electrocatalytic microbial fuel cell for degradation of methyl orange along with power production by using simple carbon paper as electrode was studied by Han et al [111].The result was very poor in terms of power density, i.e., 0.119 W/m 2 but the degradation efficiency was much better i.e., around 84.5% from mixed anaerobic sludge of wastewater. The graphene oxide supported the degradation of green dye through MFC was studied by Khalid et al [112]. It successfully removed the green dye and proved that bioactive properties of graphene oxide on the anode is superior in character to achieve 80 degradation rates.…”

A wide variety of pollutants are discharged into water bodies like lakes, rivers, canal, etc. due to the growing world population, industrial development, depletion of water resources, improper disposal of agricultural and native wastes. Water pollution is becoming a severe problem for the whole world from small villages to big cities. The toxic metals and organic dyes pollutants are considered as significant contaminants that cause severe hazards to human beings and aquatic life. The microbial fuel cell (MFC) is the most promising, eco-friendly, and emerging technique. In this technique, microorganisms play an important role in bioremediation of water pollutants simultaneously generating an electric current. In this review, a new approach based on microbial fuel cells for bioremediation of organic dyes and toxic metals has been summarized. This technique offers an alternative with great potential in the field of wastewater treatment. Finally, their applications are discussed to explore the research gaps for future research direction. From a literature survey of more than 170 recent papers, it is evident that MFCs have demonstrated outstanding removal capabilities for various pollutants.

“…e biggest chemical class of synthetic dyes is made up of azo dyes, which are abundant in the effluent of textile and dye manufacturing industries. It is very crucial to get rid of dyes from these effluents before release as the presence of high dye concentrations will result in very serious environmental issues like blocking the transfer of oxygen and light into water, which will gravely affect aquatic life [63]. Other than that, in nature, dyes can be toxic; thus, in recent years, a lot of efforts are put into using dyes as an MFC substrate for removal of color from wastewater containing dye with simultaneous electricity production.…”

A new bioelectrochemical approach based on metabolic activities inoculated bacteria, and the microbial fuel cell (MFC) acts as biocatalysts for the natural conversion to energy of organic substrates. Among several factors, the organic substrate is the most critical challenge in MFC, which requires long-term stability. The utilization of unstable organic substrate directly affects the MFC performance, such as low energy generation. Similarly, the interaction and effect of the electrode with organic substrate are well discussed. The electrode-bacterial interaction is also another aspect after organic substrate in order to ensure the MFC performance. The conclusion is based on this literature view; the electrode content is also a significant challenge for MFCs with organic substrates in realistic applications. The current review discusses several commercial aspects of MFCs and their potential prospects. A durable organic substrate with an efficient electron transfer medium (anode electrode) is the modern necessity for this approach.

“…[56] Instead, carbon materials with nano-structures possess the following merits -large surface area, high mechanical robustness, fast charge transport and admirable biocompatibility. [57][58][59][60][61][62][63][64][65][66][67] The two representativescarbon nanotubes (CNTs) and graphene-based carbon materials and their composites have been well studied as a promising anode for MFCs, which will be illustrated in the following section.…”

“…The existence of epoxy, hydroxyl and carboxyl group benefits the adsorption of bacteria and a satisfactory power density of 0.04 mW cm À 2 was delivered. [65] Alternatively, coating a layer of biocompatible polymer can modulate the toxicity of graphene, such as tween and amyloid. [10] Zhou et al [125] applied the extract of Eucalyptus leaves to treat the graphene, turning the surface to be more hydrophilic and biocompatible.…”

site). The relationship is demonstrated in depth between the physicochemical properties of the anode surface/interface/bulk (porosity, surface area, hydrophilicity, partical size, charge, roughness, etc.) and the bioelectrochemical performances (electron transfer, electrolyte diffusion, capacitance, toxicity, start-up time, current, power density, voltage, etc.). An outlook for future work is also proposed.
