Ultrasonochemical-Assisted Synthesis of CuO Nanorods with High Hydrogen Storage Ability
Figure 2
(a) N2 adsorption-desorption isotherm of the as-obtained CuO nanorods. (b) Pore-size distribution curve obtained from the desorption data. (c) Charge-discharge curves of CuO nanorods at a constant current density of 30 mA/g. (d) Cycle life of the as-synthesized CuO nanorod electrode. (e) and (f) Charge-discharge curves of CuO nanorod bundles obtained by adding 4 mL NaOH while keeping other reaction conditions unchanged and 1D CuO nanostructures obtained when 50 mL ethanol were added at a constant current density of 30 mA/g.
