Nanomodified NiFe- and NiFeP-carbon felt as anode electrocatalysts in yeast-biofuel cell

Enhancing the response of microbial fuel cell based toxicity sensors to Cu(II) with the applying of flow-through electrodes and controlled anode potentials

“…In addition to Cu(II), cautions should be taken when applying MFC-based toxicity sensors to other toxic agents such as V (V), Cr (VI), Ag (I), Hg (II) and azide, with redox potentials higher than the operating anode potentials of typical MFCs. Furthermore, the effect of electrodeposition on the cytotoxicity to the electrogenic microorganisms (Hubenova et al, 2011) and the long-term operation of the sensor should be taken into consideration in the future research.…”

Novel nanostructured electrocatalysts for hydrogen evolution reaction in neutral and weak acidic solutions

“…Nickel-iron (NiFe), nickel-iron-phosphorous (NiFeP) and nickel-iron-cobalt-phosphorous (NiFeCoP) nanostructures were electrodeposited on carbon felt (SPC-7011, 30 g/m 2 , Weibgerber GmbH & Co. KG) by applying potentiostatic and galvanostatic pulse plating techniques [16,17]. NiFe and NiFeP electrodeposits were obtained as described elsewhere [17].…”

“…NiFe and NiFeP electrodeposits were obtained as described elsewhere [17]. NiFeCoP nanostructures were produced from electrolyte containing 40 g/l NiSO 4 .6H 2 O, 40 g/l NiCl 2 .6H 2 O, 30 g/l FeS-O 4 .7H 2 O, 5 g/l CoSO 4 .7H 2 O, 11 ml 50% H 3 PO 4 , 4 g/l Na 2 H 2 PO 2 , 26 g/l b-alanine and 26 g/l glycine (SigmaeAldrich, !99.0% purity).…”

Yeast as a Biocatalyst in Microbial Fuel Cell

“…The authors related the improvement in the cell performance to the existence of Ni ions, which acted as an electron acceptor and/or due to adaptive mechanism which enhanced electron transfer through the yeast membrane. In another study, the authors prepared carbon felt modified with NiFe and NiFeP using the same preparation method [56]. They found Figure 10.…”

“…Several yeast strains have been studied as biocatalysts in MFC with or without external mediator such as Saccharomyces cerevisiae (S. cerevisiae) [41][42][43][44][45][46][47][48][49][50][51][52], Candida melibiosica 2491 (C. melibiosica) [53][54][55][56], Hansenula anomala (H. anomala) [40], Hansenula polymorpha (Hansenula polymorpha) [57], Arxula adeninivorans (A. adeninivorans) [58] and Kluyveromyces marxianus (K. marxianus) [59].…”
