Figure 11

(A) Pseudo-steady state polarization curves of the Cu-(PTA) MOFs/MgAl-LDH/CPE obtained in (a) 13, (b) 26, (c) 40, (d) 53, (e) 66 and (h) 88 mM FA, respectively. The potential scan rate is 5 mVs−1 and rotation speed of the electrode = 3000 r/min. (B) Plot of i-1 against CFA-1 at various potentials: (a) 404.7, (b) 434.9, (c) 485.2, (d) 545.7, (d) 626.2, and (h) 817.6 mV as curves (a–f). (C) Plot of the slopes (of curves in B) vs. Exp (-nFE/RT). (D) Plot of the Ln (intercepts) (of curves in B) vs. applied potential.
