“…11.0° can be seen on the curve for GO; this peak is related to a basal spacing of stacked GO. However, for the XRD pattern for rGO-Pd, there are other five relatively obvious diffraction peaks appearing at 25.0°, 40.1°, 46.6°, 68.1°, and 82.1°, which are corresponded to the (002) plane of graphite and the (111), (200), (220), and (311) face-center cubic lattice planes of Pd, respectively [ 28 , 29 ]. The XRD result suggested that the GO was chemically reduced to rGO, and Pd nanoparticles were generated on the rGO surface.…”

Graphene based 2D nanomaterials have attracted increasing attention in biosensing application due to the outstanding physicochemical properties of graphene. In this work, palladium nanoparticles (Pd) loaded reduced graphene oxide (rGO) hybrid (rGO-Pd) was synthesized through a facile method. Laccase (Lac) was immobilized on rGO-Pd by utilizing the self-polymerization of dopamine, which generated polydopamine (PDA). The PDA-Lac-rGO-Pd nanocomposites were further modified on electrode surface to construct novel biosensing platform. The obtained electrochemical biosensor was applied in the detection of catechol, achieving excellent analytic results. Under the optimum condition, this biosensor possessed a linear range from 0.1 µM to 263 µM for catechol detection, the sensitivity reached 18.4 µA mM−1, and the detection limit was as low as 0.03 µM. In addition, the biosensor also showed good repeatability, reproducibility, anti-interference, and stability. Moreover, the novel Lac based biosensor was successfully used in the trace detection of catechol existing in real water environment.

“…Metal‐free electrocatalysts derived from PPY/graphene composites have been frequently reported. Choi's group prepared the synthesis of reduced graphene oxide (rGO) decorated with nitrogen‐doped carbon nanowires (rGO‐CN) by using rGO and PPY. rGO‐PPY composites were formed by in situ polymerization of pyrrole monomer in the presence of rGO, followed by the carbonization of rGO‐PPY composites at 800 °C.…”

Developing nonprecious electrocatalysts for efficient oxygen reduction reactions (ORR) has aroused increasing interest recently. Doped nanocarbons derived from conducting polymers have emerged as a competitive class of nonprecious‐metal catalysts for the ORR because of their promising catalytic activities, long‐standing stability, and particularly low‐cost and facile preparation at a large scale via simple approaches. This review summarizes the recent progress of the preparation and application as ORR electrocatalysts of heteroatom doped nanocarbons derived from conducting polymers, and transition metal and heteroatom‐codoped nanocarbons from conducting polymers and metal salts. Finally, the challenges and further development of this field are also discussed.
