Comparison of Faradaic efficiency (FE%) values. Comparison of Faradaic efficiency (FE%) values for formate and H2 with three micro-Bi samples (micro-Bi-180s, micro-Bi-300s, and micro-Bi-1800s) as determined by 30 min of chronoamperometry under a constant CO2 flow at four different potential bias conditions (−0.776, −0.976, −1.176, and −1.376 V vs RHE).
