Ultrafine Ag/MnOx nanowire-constructed hair-like nanoarchitecture: In situ synthesis, formation mechanism and its supercapacitive property

In this work, novel hair-like (HL) nanoarchitectures constructed by ultrafine MnOx nanowires (∼7 nm) entrapped with Ag nanoparticle were first synthesized by facile in situ reaction between Ag nanowires and KMnO4, and a following hydrothermal method. The as-prepared HL Ag/MnOx nanocomposites as electrode delivered a high specific capacitance and good cycle stability.218
