Energy Storage Performance of Nitrogen Doped Reduced Graphene Oxide/Co-Doped Polyaniline Nanocomposites

The design and exploration of carbon-based electrode materials have become highly significant for developing supercapacitor technology, which has attracted considerable attention in energy storage systems. Here, nitrogen-doped reduced graphene oxide (N-rGO) – Polyaniline (PANI) nanocomposites were synthesized by a facile two-step method situ polymerization aniline monomer was performed on hydrothermally N-rGO nanosheets DBSA H2SO4 medium co-doping PANI chains. effects various acid concentrations (DBSA:H2SO4 0.5 ? 0.25:1 n/n) N-rGO:aniline ratios (N-rGO:aniline 1:4–10 m/m) used the preparation material capacitive properties investigated. It is found that co-doped N-rGO-PANI exhibit high specific capacitance 346.3 F g? 1 at A 1, remarkable rate capacity (99.9%, 1–10 1) excellent cycle stability 5 (81.3%, 5000 cycles) two-electrode system. As result, constructing chains N-doped rGO provided viable simple way to improve performances supercapacitors.
