  From the article supplement: In typical electrolyzer stacks, it is difficult to trigger light-induced COM due to the limited penetration of light. Recently, Zhang et. al. developed a redox decoupled water splitting device which can facilitate the COM mechanism in electrolyzer stacks. It enables the decoupling of HER and OER from the electrodes to spatially separated catalyst bed reactions via a pair of redox mediators. Oxygen evolution for this redox decoupled water splitting device occurs at the oxygen evolution tank, which can be made of transparent material. This option of choosing transparent material for the construction of the oxygen evolution tank implies the possibility of actualizing our proposed COM in this redox decoupled water splitting device. Furthermore, the electrocatalyst powders can be directly dispersed in the electrolyte without the need to coat on a substrate. This can then enable the effective utilization of light by the catalyst, and the photon can then be used to effectively trigger COM. Thus, based on these considerations, the proposed COM can be actualized in this redox coupled water-splitting technology.
