Abstract

Abstract : Hybrids PPy/Ni–Co LDH are used for supercapacitors and show high specific capacitances via synergistic effects between Ni–Co LDH and PPy. Abstract : Hybrid materials PPy/Ni–Co LDH based on polypyrrole nanotubes and Ni–Co LDH from ZIF-67 templates were employed as electrode materials for supercapacitors, where Ni–Co LDH possesses a hollow structure. With the help of appreciative composition and a hollow structure, the optimum PPy/Ni–Co LDH shows an excellent performance with high specific capacitances (4.4 C cm −2 at 1 mA cm −2 and 3.35 C cm −2 at 20 mA cm −2 ).
