    Influence of nitrogen doping on the electrocatalytic activity of Ni-incorporated carbon nanofibers toward urea oxidation حسب Barakat, Nasser A.M.

    منشور في 2017
    "…However, the electrochemical measurements indicated that the content of the urea in the initial electrospun solution should be optimized as the results showed that the best nickel surface activation as well as the maximum observed current density can be achieved when the urea content is kept at 5 wt%. Typically, the observed current densities using 1.0 M urea (in 1 M KOH) were 3.15, 29.7, 13.75, 47.55, 14.13 and 9.85 mA/cm2 for the nanofibers obtained from electrospun solutions having 0, 1, 2, 5, 7 and 9 wt% urea, respectively. …"
