Nevertheless, are existing different challenges for avoid the restacks between their sheets and presented a semiconducting behavior due to their interaction with the medium, etc. Is for this what hybrids materials based on graphene could also offer great advantages for different applications for energy as for example electrochemical capacitors, solar cells, etc. In this work was obtained hybrid materials based on GO/ PMo12/conducting polymer, conducting polymer/PMo12 andGO/ PMo12. The OG was obtained by Brodie method and thermally reduced. The method that was used for polymerization of monomers (pyrrole and aniline) was interfacial. For the cases of conductive polymer/PMo12, the ratio was 16.6% monomer and 83.4 % of PMo12 of weight while GO/ PMo12/conducting polymer this ration was of 10, 50 and 40% in weight, respectiv...

EIS were performed on the anode chamber, biofilm (without anolyte) and anolyte (without biofilm). Nyquist plots of the EIS data were fitted with two equivalent electrical circuits to estimate the contributions of intrinsic resistances to the overall internal MFC impedance at weeks 1 and 20, respectively.ResultsThe results showed that the system tended to increase power density from 15¿±¿3 (week 1) to 100¿±¿11 mW/m2 (week 20) and current density 211¿±¿7 (week 1) to 347¿±¿12 mA/m2 (week 20). The Samples were identified by pyrosequencing of the 16S rRNA gene and showed that initial inoculum (week 1) was constituted by Proteobacteria (40%), Bacteroidetes (22%) a...
