Synthesis and application of polypyrrole/carrageenan nano-bio composite as a cathode catalyst in microbial fuel cells

Polypyrrole-Grafted Coconut Shell Biological Carbon as a Potential Adsorbent for Methyl Tert-Butyl Ether Removal: Characterization and Adsorption Capability

“…The band at 1471 cm −1 is attributed to the C-N stretching vibration in the pyrrole ring. Additionally, the peaks at 1296, 1168, and 1032 cm −1 are ascribed to the in-plane -C-H vibrations, and the peak at 910 cm −1 is for the =C-H out-of-plane vibration [18,21]. This indicated that the backbone of PPy/GAC is similar to that of PPy prepared by the conventional route, and PPy was successfully sorbed throughout the pore matrix of the GAC [18].…”

Graphene/poly(3,4-ethylenedioxythiophene)/Fe3O4 nanocomposite – An efficient oxygen reduction catalyst for the continuous electricity production from wastewater treatment microbial fuel cells

“…Esmaeili et al, developed the polypyrrole/carrageenan ORR catalyst via a chemical polymerization technique and the prepared catalyst equipped dual chamber MFC generated the power density of 72.1 mW/m 2 in Palm oil mill effluent anaerobic sludge [58]. Ahmed et al, employed the polyaniline nanofiber/carbon black ORR catalyst in ACMFCs, which exhibited the maximum power output of 496 mW/m 2 in anaerobic sludge [59].…”

Power generation and wastewater treatment using a novel SPEEK nanocomposite membrane in a dual chamber microbial fuel cell

“…The media contained 3 g of glucose, 0.07 g of yeast extract, 0.2 g of KCl, 1 g of NaH 2-PO 4 .4H 2 O, 2 g of NH 4 Cl, and 3.5 g of NaHCO 3 (all from Merck), while 10 ml of Wolfe's mineral solution and 10 ml of Wolfe's vitamin solution were added per litre. All these experiments were conducted at 30 C in an incubator.…”

“…However, there are still some obstacles to the commercial production of MFCs. The performance of MFCs depends on different factors, including the bacterial composition, electrodes, cathode catalyst, media, and ion exchange membranes [4].…”
