Performance of driven synthesis. a Efficiency (ηds) of driven synthesis as function of \({\cal{F}}_{{\mathrm{fuel}}}\) and kext. Regions of operating regimes that do not perform driven synthesis are colored in gray. The yellow dashed (resp. orange solid) line denotes the maximum of ηds (resp. \(- \dot W_{{\mathrm{ext}}}\), see also Supplementary Fig. 2) versus kext, while the black solid line corresponds to ηds = 0. b, c (resp. d, e) Concentrations and currents as a function of kext (resp. \({\cal{F}}_{{\mathrm{fuel}}}\)) along the line \({\cal{F}}_{{\mathrm{fuel}}} = 7.5 \cdot RT\) (resp. kext = 1 s−1) highlighted by blue vertical (resp. horizontal) dotted line in plot (a). Kinetic constants and standard chemical potentials are the same as for ES analysis (see Supplementary Information). Note that J3 = Iext + J4 always holds, where J3 = J3F + J3W is the net current flowing from \({\mathrm{A}}_2^ \ast\) to \({\mathrm{A}}_2\)
