The kinetic rates will also be dictated by the maximum solubility of oxygen in the solvent. Therefore, we investigated the system at higher pressures to discern if further intensification can be possible with a more intense light source in the future, when we plan to further optimize this system. From Fig 7, it can be observed that at a higher pressure, i.e., with a higher limit for the dissolved oxygen concentration, we reach what appears to be kinetically limited regimes at lower rotation speeds. Even at low rotation speeds, the mass transfer limitations can be easily overcome. Therefore, if the photon flux were to be increased for these cases, the productivity could be improved even further.
