“…The results demonstrate an improved electron transfer for the NiO-CuO/G electrode (A. Esfandiari, M. Kazemeini 2016). The distribution of electron transfer numbers con rms that the NiO-CuO/G could be improved towards ORR and thus improving the performance of cathode in MFCs in neutral media.…”

Mixed transition metal (Ni & Cu) oxides supported on graphene (NiO-CuO/G) electrocatalyst was fabricated and tested as an efficient and cost-effective cathode for oxygen reduction reaction (ORR) in microbial fuel cells (MFCs). The electrocatalytic activity and selectivity of the NiO-CuO/G for ORR were examined using linear sweep voltammetry measurements (LSV) on a rotating disc electrode (RDE) in pH-neutral electrolyte. In comparison with a benchmark platinum cathode, the NiO-CuO/G showed high selectivity towards the ORR. The analysis of Koutecky-Levich relationship suggests that the electrocatalyst follows the four-electron ORR pathway. NiO-CuO/G cathode in an air-cathode MFC exhibited a slightly lower power density 21.25 mWm− 2 compared to 50.4 mW m− 2 for Pt/C. Both scanning and transmission electron microscope analyses of anodic biofilm showed that a thick biofilm was successfully developed with a rod-like shape. Biochemical characterization of the communities showed that four genera named Escherichia coli (E-coli), Shewanella putrefaciens, Bacillus cereus and Bacillus Thuringiensis/mycoides, which belonging to GammaProteobacteria and Firmicutesphylathatwerethe most abundant bacteria in the anodic biofilm. Our results revealed that NiO-CuO/G cathode demonstrates an enhanced electrocatalytic activity toward ORR in a pH-neutral solution; thus, the newly developed mixed transition metal oxides electrocatalyst can replace other expensive Pt-based catalysts for MFC application.

“…Nonetheless, to invent a new metal NPs composite catalyst, the characteristics and properties of respective metal components and the cost of manufacturing that catalyst should be taken into consideration. Recently, there are a lot of research done on synthesis of various metal NPs to investigate their electro-catalytic performance in fuel cell [12][13][14]. In this research paper, Sn and Ag are selected to be synthesized to be bimetallic NPs composite which works as fuel cell catalyst.…”

In this research, Sn/Ag nanoparticle composite was produced by using chemical reduction method with the aids of sodium borohydride as reducing agent and sodium succinate as protective agent. The XRD, EDX, and TEM analyses showed that the Sn/Ag nanoparticle composite was formed with an average particle size of 4.37 + 0.44 nm. For the application, LSV analysis was done on Sn nanoparticle and Sn/Ag nanoparticle composite samples, and the analysis showed current produced from Sn/Ag nanoparticle composite (4.10 × 10-6 A) is higher than Sn nanoparticle (3.47 × 10-6 A) at the potential of -0.83V.
