摘要: Abstract We report the synthesis of a series praseodymium oxide/polypyrrole (Pr6O11/PPy) nanocomposites, and their application in electrochemical energy storage. The Pr6O11/PPy nanocomposites were synthesized by situ surface-initiated polymerization technique based on amine-functionalized Pr6O11 nanoparticles. exhibit well-defined core/shell structure observed transmission electron microscopy (TEM) scanning microscope (SEM). Thermogravimetric analysis reveals significantly enhanced thermal stability with addition Furthermore, they possess weak temperature dependence conductivity highest specific capacitance 400 F g−1 at charge–discharge current density 10 mA cm−2 1.0 M NaNO3 electrolyte solution when being used as electrode material for supercapacitor.
