Synthesis and Electrochemical Performance of Molybdenum Disulfide-Reduced Graphene Oxide-Polyaniline Ternary Composites for Supercapacitors

Molybdenum disulfide/reduced graphene oxide/polyaniline ternary composites (MoS /rGO/PANI) were designed and synthesized by a facile two-step approach including hydrothermal and polymerization process. The MoS /rGO/PANI composites presented an interconnected 3D network architecture, in which PANI un...

Description
Summary:Molybdenum disulfide/reduced graphene oxide/polyaniline ternary composites (MoS /rGO/PANI) were designed and synthesized by a facile two-step approach including hydrothermal and polymerization process. The MoS /rGO/PANI composites presented an interconnected 3D network architecture, in which PANI uniformly coated the outer surface of the MoS /rGO binary composite. The MoS /rGO/PANI composites with a weight percent of 80% (MGP-80) exhibits the best specific capacitance (570 F g at 1 A g ) and cycling stabilities (78.6% retained capacitance after 500 cycles at 1 A g ). The excellent electrochemical capacitive performance is attributed to its 3D network structure and the synergistic effects among the three components that make the composites obtain both pseudocapacitance and double-layer capacitance.
