In situ fabrication of electrically conducting bacterial cellulose-polyaniline-titanium-dioxide composites with the immobilization of Shewanella xiamenensis and its application as bioanode in microbial fuel cell

The electrical conducting bacterial cellulose/polyaniline (BC/PANI) based composites were synthesized over in situ polymerization of aniline onto BC with ammonium-persulphate (APS) and chloride hexahydrate iron (III) as oxidant (FeCl3·6H2O). conductivity was improved the presence a titanium-dioxide (TiO2) coating. BC/PANI/TiO2/APS 3.7 S/m compare 2.9 2.67 BC/PANI/TiO2/FeCl3·6H2O BC/PANI/APS, respectively. Moreover, when using anode immobilization Shewanella xiamenensis, an efficiency microbial fuel cell observed. power-density maximized 38.89 W/m3 compared 2.57 case bare anode. These results will serve good base for development compact high power density.
