摘要: The conductive polypyrrole (PPy)/reduced graphene oxide (rGO) composites were synthesized through simple, environmentally benign, time and cost efficient, in situ polymerization bioreduction techniques. pyrrole monomer effectively adsorbed over the negatively charged GO sheets electrostatic π–π interactions was polymerized into its state. obtained morphological images of rGO/PPy composite ensured that entire surface active carbon support covered by PPy. removal oxygen functionalities from with aid Ocimum tenuiflorum extract ascertained FT-IR UV–vis absorption spectroscopic studies. exhibited higher electrocatalytic oxidation current as evidenced cyclic voltammetric analysis. number actives sites continuous carrier channels a maximum MFC power density 1068 mW/m2, which is almost two-fold than bare strong a...
