Carbon‐Based Composites as Anodes for Microbial Fuel Cells: Recent Advances and Challenges

Abstract

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.

Anode Modification with Fe2O3 Affects the Anode Microbiome and Improves Energy Generation in Microbial Fuel Cells Powered by Wastewater

“…Studies report that modifying the anode electrode with Fe 2 O 3 changes the surface from smooth to rough, improving the microorganisms' attachment [6]. Additionally, the hydrophobic carbon surface can be hydrophilized by coating with Fe 2 O 3 due to the hydrogen bond formed between the Fe 2 O 3 oxygen and the water molecule [7]. The advantages of choosing this 2 of 21 material are its easy availability, chemical stability, and low cost.…”

Chitosan-Based Molecularly Imprinted Polymer Modified Zinc Oxyde/Graphene Nanocomposite/Screen Printed Carbon Electrode for Electrochemical Detection of Methyl Paraben

“…13,[25][26][27] Carbon-based materials are also reported to have unique characteristics, such as fast electron transfer, good electrical and thermal conductivity, and a large surface area. [28][29][30][31][32][33][34] Studies have reported that hybridization of metal or metal oxide with a carbonaceous material can provide a synergistic effect between the two components. 13,14,30,35 For example, a hybridization of ZnO nanoparticles on graphene has demonstrated excellent performance in the detection of H 2 S at 1-2 ppm.…”
