Peroxidase biocathodes for a biofuel cell development

Journal of Renewable and Sustainable Energy, 2010
In terms of sustainable energy production, enzymatic biofuel cells are attractive for a number of special applications, such as disposable implantable power suppliers for medical sensor-transmitters and drug delivery/activator systems and self-powered enzyme-based biosensors; they offer practical advantages of using abundant organic raw materials as ...

Biocathodic Nitrous Oxide Removal in Bioelectrochemical Systems

Environmental Science & Technology, 2011
Anthropogenic nitrous oxide (N(2)O) emissions represent up to 40% of the global N(2)O emission and are constantly increasing. Mitigation of these emissions is warranted since N(2)O is a strong greenhouse gas and important ozone-depleting compound. Until now, only physicochemical technologies have been applied to mitigate point sources of N(2)O, and no ...

Laccase-based biocathodes: Comparison of chitosan and Nafion

Analytica Chimica Acta, 2016
Chitosan and Nafion(®) are both reported as interesting polymers to be integrated into the structure of 3D electrodes for biofuel cells. Their advantage is mainly related to their chemical properties, which have a positive impact on the stability of electrodes such as the laccase-based biocathode.

Evaluation of biocathode materials for microbial electrosynthesis of methane and acetate

Bioelectrochemistry, 2022
This study compares carbon felt (CF), granular activated carbon (GAC), and a conductive acrylonitrile butadiene styrene (cABS) polymer cathodes for CH4 and acetate production in a microbial electrosynthesis (MES) cell. At an applied voltage of 2.8 V and continuous CO2 flow, the CF biocathode MES cell showed the highest CH4 production rate of 1420 ± 225

Role of Biocathodes in Bioelectrochemical Systems

2017
Environmental damage, depleting fossil fuels and energy security are major factors driving intensive research efforts to develop carbon neutral or carbon negative technologies which can be used to produce electricity and chemicals. Technologies under development to achieve this goal include those based on bioelectrochemical, biological, thermal and ...

Biocathodic performance of bioelectrochemical systems operated at low temperature

Bioresource Technology, 2020
This study investigated the effects of operational temperature on cathodic performances of five bioelectrochemical reactors operated in parallel at 25-7 °C, and on the biofilm microbial community at the end of tests. Compared with the anodic biofilm, the cathodic biofilm has high stability subjected to temperature shift in the aspect of cathode ...

Biohydrogen facilitated denitrification at biocathode in bioelectrochemical system (BES)

Bioresource Technology, 2014
Reductive removal of nitrate in bioelectrochemical system (BES) at abiotic cathode, biocathode and biohydrogen facilitated biocathode were investigated. It was found that nitrate removal efficiency reached 95% and 59% at the biohydrogen facilitated biocathode and biocathode respectively, while which was only 13% at the abiotic cathode.

Accelerated decolorization of azo dye Congo red in a combined bioanode–biocathode bioelectrochemical system with modified electrodes deployment

Bioresource Technology, 2014
In this study, BES with bioanode and biocathode was applied to decolorize an azo dye Congo red (CR). Results showed that the Congo red decolorization efficiency (CR-DE) within 23 h in a combined bioanode-biocathode single chamber BES was 98.3 +/- 1.3 ...

Hydrogen production in microbial electrolysis cells with biocathodes

Trends in Biotechnology
Electroautotrophic microbes at biocathodes in microbial electrolysis cells (MECs) can catalyze the hydrogen evolution reaction with low energy demand, facilitating long-term stable performance through specific and renewable biocatalysts. However, MECs have not yet reached commercialization due to a lack of understanding of the optimal microbial strains
