Shulei Chou

Porous vanadium oxide (VO_x) and MnO₂ nanowires were synthesized by an electrochemical deposition method using stainless steel mesh as substrate. The as-prepared porous VO_x and MnO₂ nanowire films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy. The cyclic voltammetry (CV) results show that the MnO₂ nanowire film shows specific capacitance of 195, 170, 158, and 91 F g^-1 at scan rates of 5, 10, 20, and 50 mV s^-1, respectively. The porous VO_x film displays specific capacitance of 152, 124, 99, and 76 F g …
