Fig. 4. (A) Surface concentration (Γ) of the prepared electrodes vs. Ni percent (mol%) in the deposition bath. (B) The variation of glycerol electrooxidation current recorded at 0.65 V (vs. SCE) with different Ni percent (mol%). (C) The variation of glycerol electrooxidation current at 0.65 V (vs. SCE) for various metal loadings in 0.2 M NaOH solution containing 8 mM glycerol of NiCu@CF, CuNi@CF, Ni@CF, Cu@CF, and Ni85%Cu15%@CF electrodes.
