Figure 3From: Nitrogen-doped, FeNi alloy nanoparticle-decorated graphene as an efficient and stable electrode for electrochemical supercapacitors in acid medium CV curves. CV curves of Gr (a), N-doped Ni@Gr (b), and N-doped FeNi@Gr (c) in 1 M H2SO4 solution at different scan rates, and comparison CV for the fabricated materials at a sweep rate of 10 mV s−1 (d).Back to article page
