Macroporous composite capacitive bioanode applied in microbial fuel cells

Chinese Chemical Letters, 2020
Abstract Interfacial electron transfer between electroactive biofilm and the electrode was crucial step for microbial fuel cells (MFCs). A three-dimensional multilayer porous sponge coating with nitrogen-doped carbon nanotube/polyaniline/manganese dioxide (S/N-CNT/PANI/mnO2) electrode has been developed for MFC anode.

Deciphering the differentiated performance on electricity generation and COD degradation by Rhodopseudomonas-dominated bioanode in light or dark.

Chemosphere
Anoxygenic phototrophic bacteria is a promising catalyst for constructing bioanode, but the mixed culture with non-photosynthetic bacteria is inevitable in an open environment application.

Effects of Carbon Nanotube Paper Properties on Enzymatic Bioanodes

Electroanalysis, 2013
AbstractCarbon papers are frequent current collectors in fuel cells, but recently carbon nanotube papers have been introduced as new types of carbon paper. They have varying thickness, surface area, density, gas permeability, and conductivity. This paper studies the effect of these properties on electrochemical performance.

A metallacarborane redox mediator for an enzyme-immobilized chitosan-modified bioanode

Bioelectrochemistry, 2010
We describe here the first report of a metallacarborane complex as a redox mediator in a functioning biofuel cell. Specifically, we have prepared a water-soluble salt of the complex anion [commo-3,3'-Fe-(closo-2,1-C(2)B(9)H(11))(2)](-) and employed it as a redox mediator for glucose oxidation using chitosan/multiwalled carbon nanotube-modified ...

Lead(II) Removal at the Bioanode of Microbial Electrolysis Cells

ChemistrySelect, 2016
Abstract Advanced treatment, such as tight membrane filtration and ion exchange, can be applied for Pb 2+ removal from wastewater but these methods are expensive with a high demand for electric energy and chemicals.

Two‐Stage Oxidation of Glucose by an Enzymatic Bioanode

Fuel Cells, 2013
AbstractThe present study reports the design of a novel bioanode to deeply oxidize glucose in an enzymatic biofuel cell (EFC). This enzymatic glucose cell utilizes three co‐immobilized enzymes: NAD‐dependent glucose dehydrogenase (GDH), NAD(P)+‐dependent gluconate‐5‐dehydrogenase (Ga5DH), and diaphorase (DI).

(Keynote) Utilizing Bioengineering for Fabricating Catalytic Cascade Bioanodes

ECS Meeting Abstracts, 2016
Over the last decade, there have been major developments in materials engineering for bioelectrodes (i.e. bioanodes and biocathodes in biofuel cells and biosensors), including the engineering of nanomaterials and nanostructured electrodes for increasing electrochemically active surface areas and increasing the rate of direct electron transfer. However,

Stainless Steel-Based Bioanodes for Applications in Bioelectrochemical Systems

ECS Meeting Abstracts, 2018
The majority of studies focusing on bioelectrochemical systems (BES) report the utilization of carbon-based electrodes. However, in order to overcome the limitations related to the scale-up of Microbial Fuel Cells (MFC) and Microbial Electro Synthesis (MES) cells technologies, the utilization of metal-based electrodes need to be considered due to ...
