In actual photosynthesis, Z scheme excitation is performed to separate electronic charge with high efficiency by using solar light. In this study, water splitting into and on dye modified was investigated and it was found that and formation rate is much improved by dye modification. Charge separation mechanism was further studied with transient spectroscopy and this study reveals that photo excitation in Cr-tetraphenyl porphyrin is analogous with Z scheme in photosynthesis and complete charge separation was achieved at room temperature.
