Abstract
Chromium metal is a potential toxin released by various industries as by products. Reduction of the same costs an ample amount of manpower and wealth. Alternate, economical, efficient, and sustainable form of chromium reduction while generating electricity is a boon that microbial fuel cell (MFC) has provided to man. It paves way for an attractive technique to process hazardous elements. Nature as well as the type of electrode modulates the efficiency of reduction and power production. Many previously published studies have reviewed chromium removal from effluents as well as through MFCs, but utilization of nanoparticle-based MFC for chromium removal has not been exclusively done before. Hence, the objective of the current review is to provide exclusive study on nanoparticle-assisted MFC for chromium reduction. Reputed published data from the past 5 years have been studied meticulously to compare the best outcomes of MFC in chromium removal. Chromium is found to be removed mostly in double-chambered MFC with a maximum removal of 100% when iron is used as an electrode. Removal of the same has led to generation of maximum power of 1965.4 mW m-2 when palladium nanoparticles are used at the electrode. Removal rates of Cr(VI) from a mixture of NiCo2O4, MoS2, and graphite felt in a dual-chamber MFC showed an 8.13% increase after 24 h of light exposure. Another efficient setup used MoS2 nanosheets and Alpha-FeOOH nanoparticles in a dual-chamber MFC to completely remove Cr(VI) and achieve a high removal ratio of 91.45%. The current study reviews the recent updates in chromium reduction through MFC and its significance in future as a potential instrument for bioremediation and energy source.

Abstract
: Although microbial fuel cells (MFCs) have been developed over the past decade, they still have a low power production bottleneck for practical engineering due to the ineffective interfacial bioelectrochemical reaction between exoelectrogens and anode surfaces using traditional carbonaceous materials. Constructing anodes from biomass is an effective strategy to tackle the current challenges and improve the efficiency of MFCs. The advantage features of these materials come from the well-decorated aspect with an enriched functional group, the turbostratic nature, and porous structure, which is important to promote the electrocatalytic behavior of anodes in MFCs. In this review article, the three designs of biomass-derived carbon anodes based on their final products (i.e., biomass-derived nanocomposite carbons for anode surface modification, biomass-derived free-standing three-dimensional carbon anodes, and biomass-derived carbons for hybrid structured anodes) are highlighted. Next, the most frequently obtained carbon anode morphologies, characterizations, and the carbonization processes of biomass-derived MFC anodes were systematically reviewed. To conclude, the drawbacks and prospects for biomass-derived carbon anodes are suggested.
