8 The CO2 reduction reaction using a renewable energy source is a promising strategy for 9 its utilization. Such a technology however requires the development of catalysts with 10 optimized activity and selectivity that can be integrated into the device architectures. 11 Flow electrolyzers have recently been proposed for facilitating the electrochemical CO2 12 reduction reaction thanks to their unique ability to perform electroreduction at high 13 reaction rates via the creation of three-phase interface. While some examples of flow 14 electrolyzers for the conversion of CO2 has recently been reported, the influence of the 15 CO2 and electrolyte streams on the overall catalytic mechanism is remained ambiguous. 16 Here, we synthesized single-atom nickel on two-dimensional nitrogen-doped carbon 17 nanosheets (SA Ni-NC) for the CO2-to-CO conversion. Taking advantage of this model 18 catalyst, we explored the correlation between the applied potential and the feeds in both 19 3 electrolyte and CO2 on the one hand, and the performance metrics on the other hand. 1 By regulating the feed stream’s conditions, the SA Ni-NC achieves energy efficiencies 2 as high as 85% at jCO = 7.2 mA cm -2 and 56% at jCO = 170 mA cm -2 whereas the single3 pass CO2-to-CO conversion efficiency (SPCC) reaches 2.6% cm . We finally 4 demonstrated the scalability of the flow electrolyzers by stacking three 1-cm reactors 5 and reached a record-high CO yield rate of 31.5 L min m with near-unity CO 6 selectivity and an SPCC of 8.9% from three. 7
