From: Direct formation of copper nanoparticles from atoms at graphitic step edges lowers overpotential and improves selectivity of electrocatalytic CO2 reduction

Fig. 3

a FE of formate obtained for the Cu/GNF under the potential ranges between -0.78 V to -0.38 V, b FE and the current density of Cu/GNF (0.84 wt% Cu) over time at a constant bias of -0.38 V vs RHE, c LSV of freshly prepared GNF, Cu/GNF and Cu/GNF after 24 h CO2RR recorded with 10 mV s-1 scan rate in 0.1 M KHCO3, and d Zoomed version of c showing the onset potential of the tested catalysts. Error bars are made from three replicate measurements.
