biofouling inhibition on nano silver Ferrous Sulfide partly graphitized carbon cathode with enhanced catalytic activity and durability for microbial fuel cells
Carbon, 2017Co-Authors: Ye Sun, Ying Dai, Yaqiang Duan, Liu Yang, Jinlong ZouAbstract:Abstract In single-chamber microbial fuel cells (SC-MFCs), microorganisms attached on air-cathode can suppress catalyst activity and electron/proton transport to lower oxygen reduction reaction (ORR) efficiency. To enhance power output of SC-MFCs, an efficient way is to improve durability of ORR catalyst by inhibiting bacterial overgrowth on cathode. Silver/Ferrous Sulfide/partly-graphitized carbon (Ag/FeS/PGC) catalysts are synthesized from waste pomelo skins as carbon source. Anti-biofouling mechanisms and ORR pathways of Ag/FeS/PGC cathodes are deeply clarified. Ag/FeS/PGC (Fe: Ag of 1: 0.6) exhibits the maximum power density (1361 mW m −2 ) and the best durability with a decline of 19.9% after 90 d operation, which are better than those of Pt/C. Positively charged sites on Ag are favorable for O 2 adsorption, meanwhile the enhanced electron poverty in PGC can weaken O O bonding in O 2 , which contribute to both biofouling inhibition and ORR activity. Metallic state of FeS can be enhanced by embedding in PGC skeleton or integrating with Ag (Ag/FeS heterojunctions), which improves electrical conductivity and ORR activity of Ag/FeS/PGC. Synergistic effects among Ag, FeS and PGC contribute to the high antibacterial capacity, easy electron transport and promising ORR performance. This work provides a new idea for MFCs application using efficient antibacterial ORR catalysts.

A New Carbon/Ferrous Sulfide/Iron Composite Prepared by an in Situ Carbonization Reduction Method from Hemp (Cannabis sativa L.) Stems and Its Cr(VI) Removal Ability
ACS Sustainable Chemistry & Engineering, 2014Co-Authors: Ru Yang, Yong Wang, Li Min, Yijie HongAbstract:A facile strategy is developed to prepare carbon/Ferrous Sulfide/iron (C/FeS/Fe) composites by an in situ carbonization reduction method using agricultural waste hemp stems as the carbon precursor and ferrisulfas as the iron source. Under the reductive atmosphere generated from biomass carbonization, ferrisulphas can be in situ directly decomposed and reduced into FeS/Fe at 800 °C existing in the form of nanoparticles embedded in a carbon matrix; so this synthetic procedure is much simpler compared with traditional multistep methods. The C/FeS/Fe composite, as expected, displays an excellent Cr(VI) removal performance with a maximum capacity of 127 mg/g at pH 5 because of the adsorption on its large surface and simultaneous reducing actions that have been evidenced by XPS analysis. Although the presence of FeS/Fe gives rise to an obvious decline of BET surface area, the strong reducibility can compensate for the loss of surface area and significantly enhance Cr(VI) removal especially at a low pH. The syne...
