Variation of the photosensitiser concentration shows a peak TOFCO at 17±2 min -1 for 30 µM with clear decays at higher or lower concentration (2.0±0. With these fixed concentrations of the other components, the phosphate concentration had a minimal effect until performance decreased as surfactant solubility was visibly lowered (TOFCO 12.8±0.7, 17±2, 7 min -1 at 1, 100, 1000 mM respectively. Fig . In contrast to the catalyst concentration, the trend of the YieldCO follows the TOFCO for the photosensitiser, surfactant, reductant and buffer concentrations. However, it is not clear how to increase both the YieldCO and TOFCO for the system. Notably, the reductant and buffer concentrations significantly affect the solution ionic strength to indirectly influence micelle size and shape, as does the loading of catalyst and photosensitiser, yet varying the concentrations individually cannot capture these effects. Fully exploring the parameter space with 10 concentrations of each of the 5 variables would require a humanly impractical 10 5 experiments (SI Note 2). Thus, we employed Bayesian statistics to bring the number of experiments to an actionable number for a human experimentalist.
