摘要: Abstract The needle-like Co Mo O with multi-modal porosity was synthesized via simple strategy of chemical coprecipitation in hydrothermal condition. resulted products were characterized SEM, EDXS, XPS, XRD, Raman, BET, FTIR and electrochemical techniques. exhibited excellent performance as supercapacitor. A large capacitance value 1180 F/g obtained good cycle life from the CV plots at 5 mV/s or 302 F/g calculated discharge curve 1 A/g. may be attributed to microstructure combination microporosity, mesoporosity macroporosity which leads surface area contact probability, diffusion efficiency storage ability OH − ions. It’s observed for first time that MoO 3 gradually flows away charge-discharge. presence not directly contribute electrochemcal materials but it helps form structure thus indirectly affect O.
