Abstract
Microbial fuel cells (MFCs) can generate energy while processing organic pollutants, which has a great impact on environmental wastewater treatment applications. In this study, a gel polymer was formed by Co-Fe-N co-doping biochar (Co-Fe-N@BC), which was used as the anode material to improve the electricity generation performance of MFC. The Co-Fe-N@BC material prepared at 900℃ carbonised biomass into more graphitic carbon, and its total resistance (3.56 Ω) was significantly reduced. In the corresponding dual-chamber MFC, the current density was 2.81 A/m2, and the power density reached 1181 mW/m2 at maximum. Among the materials tested, the Co-Fe-N@BC anode MFC had the highest chemical oxygen demand removal rate and coulombic efficiency, reaching 91% and 13%, respectively. It is proved that MFC with Co-Fe-N@BC anode has the best electrochemical performance.
期刊介绍：
Environmental Technology is a leading journal for the rapid publication of science and technology papers on a wide range of topics in applied environmental studies, from environmental engineering to environmental biotechnology, the circular economy, municipal and industrial wastewater management, drinking-water treatment, air- and water-pollution control, solid-waste management, industrial hygiene and associated technologies.
Environmental Technology is intended to provide rapid publication of new developments in environmental technology. The journal has an international readership with a broad scientific base. Contributions will be accepted from scientists and engineers in industry, government and universities. Accepted manuscripts are generally published within four months.
Please note that Environmental Technology does not publish any review papers unless for a specified special issue which is decided by the Editor. Please do submit your review papers to our sister journal Environmental Technology Reviews at http://www.tandfonline.com/toc/tetr20/current
