were identified that are predicted to provide comparable performance while using 30% less catalyst and 16% less photosensitiser (Catalyst 2.7 vs. 3.9 µM; Photosensitiser 94 vs 112 µM; Surfactant 23 vs 19 CMC; Reductant 256 vs 220 mM; Buffer 402 vs 462 mM). Thereby, the dataset is further exploited to minimise the more expensive, metal-containing components at a minor performance cost, which is a key trade-off for system commercialisation (additional analysis in SI Note 3).
