“…Although platinum is currently the most effective and commonly used catalyst, its high cost and unsustainability hinders the scaling up of MFCs. Transition metal based catalysts such Mn, Co, V and their oxide forms have been used as cathode catalysts in MFCs as a replacement for platinum [2][3][4]. These catalysts have produced power comparable to Pt but they are also unsustainable and are not stable.…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Highlights of Research1. First Study to observe the influence of mitigating pH changes and its effect on laccase activity in a microbial fuel cell (MFC).2. Decoupling pH and salinity in the cathode chamber of MFC.3. Correlation of laccase activity with performance of the system. Results show that using Nafion 117 membrane limits salinity and pH changes in the cathode (100 mM acetate buffer as catholyte) leading to prolonged laccase activity and faster AO7 decolourisation compared to using CMI7000 as a membrane; similarly automatic pH control in the cathode chamber was found to be better than using 200 mM acetate buffer.It is suggested that while pH control in the cathode chamber is important, it does not guarantee sustained laccase activity; that salinity increases affect the activity and could be mitigated using a cation selective membrane.

“…Among all, vanadium oxides have attracted a number of attentions due to their promising catalytic properties, which have been extensively studied in several kinds of fuel cells, including direct alcohol fuel cells (DAFCs), [213] solid oxide fuel cells (SOFCs) [214] and microbial fuel cells (MFCs). [190] DAFCs are using alcohols as fuels, where oxygen reduction reactions (ORRs) occur on the anodes and alcohol oxidation reactions (AORs) on the cathodes. Benefit from the multiple valence states, V 2 O 5 exhibits redox and Lewis acid/base properties, which has been considered important in surface catalytic reactions.…”

“…Hieratical V 2 O 5 3D structures were used as cathode catalysts for an MFC with a power density of 6.06 W m −3 . [190] Compared with another alternative of MnO 2 , V 2 O 5 has shown superior catalytic properties and capability in wastewater treatment. However, limited to the poor electrical conductivity of V 2 O 5 , the catalytic activity of V 2 O 5 is lower than Pt in MFCs.…”

Vanadium oxides are known for their multioxidation states and diverse crystalline structures. Owing to their excellent interactions with molecules or ions, outstanding catalytic activities, and/or strong electron–electron correlations, nanostructured vanadium oxides have been extensively studied for energy conversion in the recent years. Here is a review of the recent advances in the development of nanostructured vanadium oxides and their applications. The synthesis strategies and structural properties of various vanadium oxide nanostructures, including vanadium dioxide (VO2), vanadium pentoxide (V2O5), and others, are summarized. The applications of vanadium oxides in energy conversion are discussed, focusing on three important types of energy sources: chemical energy (LIBs, pseudocapacitors and fuel cells), solar energy (photovoltaics and photocatalytic hydrogen evolutions), and heat (thermoelectric generation). Finally, conclusion with our remarks on the prospects of nanostructured vanadium oxides in energy conversion are provided.

“…The inevitable exhaustion of energy reserves necessitates the development of alternative energy sources with an impressive environmental impact, in which the influence of air cathode microbial fuel cells (ACMFCs) is impressive [1,2]. ACMFC is a renewable energy device that generates electricity through the catalytic degradation of organic substrates like glucose, acetate, lactate, starch etc., with the utilization of microbes existing in waste water [3].…”
