Template-free electro-synthesis of PbO2 nanorod with chrysanthemum-like array
2019
Abstract PbO 2 electrode is one of crucial materials in electrochemical field, however, the fabrications of nanostructured PbO 2 materials are highly confined to the template method. In this work, the nanostructured PbO 2 materials were controllably synthesized by template-free electrodeposition method. It is found that the microstructure of PbO 2 material was highly depended on the electrochemical deposition models, i.e., cyclic voltammetry (CV) method, potentiostatic method (PM), pulse potentiostatic method (PPM) and pulse galvanostatic method (PGM). Especially, PbO 2 nanorod built by nanoparticles with chrysanthemum-like array synthesized in the absence of template by pulse potential deposition method showed high specific capacitance and good stability for supercapacitor application.
