pH-dependent microkinetic modelling at the RHE-scale. (a) pH-dependent microkinetic modelling for CO2RR on Sn-based catalysts. Lower electric fields correspond to more alkaline conditions, whereas higher fields indicate more acidic conditions. (b) Rate-determining step analysis for HCOOH formation at acidic (dashed lines) and alkaline (solid lines) conditions. The purple lines indicate activity limited by the 1st electron transfer, while the green lines demonstrate limitations due to the 2nd electron transfer.
