In-situ growth of N@MoO2 microflowers on carbon cloth for high-performance anodes in microbial fuel cells

Strategic regulation of barrier characteristics of biofilms to enhance the extracellular electrogenic performance in MFCs: an electrochemical dynamic evaluation study

“…Extracellular polysaccharides are found on the anode biofilm and help in further bacterial adhesion over the electrode surface and lead to bacterial colonization. 60 Bacterial attachment and biofilm formation increase with more viable bacterial cells and the Z r value is 85.72%, and as a result the thickness of the biofilm also increases. This results in enhanced electrochemical activity.…”

Advances in Anode Materials for Microbial Fuel Cells

“…Unlike expensive precious metals, transition metal oxides have a wider range of applications in improving the overall performance of MFCs due to their low cost, good conductivity, and high capacitance. [ 103,104 ] Examples of such materials include iron oxides (Fe 3 O 4 , [ 105 ] Fe 2 O 3 , [ 106 ] and FeO [ 107 ] ), MnO 2 , [ 108 ] TiO 2 , [ 109 ] MoO 2 , [ 110 ] and RuO 2 . [ 17 ] Compared with monometallic oxides, bimetallic oxides contain metals with variable valence and have better capacitance, allowing them to temporarily store electrons released by microorganisms and enhance the cyclic stability of MFCs.…”

Fabrication of a Molybdenum Dioxide/Multi-Walled Carbon Nanotubes Nanocomposite as an Anodic Modification Material for High-Performance Microbial Fuel Cells

“…Their experimental results also indicate good electrocatalytic activity during charge transfer of the anode, and the maximum power density of the MFC is 2.06 ± 0.05 W m −2 . A previous study discussed nitrogen-doped CC grafting with MoO 2 microspheres (N@MoO 2 /CC) prepared via in situ polymerization and high-temperature carburization for the development of high-performance anodes of MFCs [ 41 ]. The N@MoO 2 /CC anode exhibited remarkable bioelectricity generation due to its dual function of promoting bacterial colonization and enriching electroactive bacteria, thereby improving the electrocatalytic activity of the anode.…”
