Figure 4. (A) LSV curves for triphase and diphase electrodes at 20 °C and 50 °C; (B) Tafel analyses of the partial current densities for formate production; (C) Apparent turnover frequency (TOF) of HCOOH production at -0.9 V vs. RHE under various temperatures; (D) Stability of In-3P electrode at -0.9 V vs. RHE and 40 °C. LSV: Linear sweep voltammetry; FE: Faradaic efficiency; RHE: reversible hydrogen electrode.
