(7) Construction of artificial Z-scheme

Fig. 7 Z-scheme.

Most of practical photocatalysts absorb UV (minor in sunlight (5%)), and does not use visible light (major in sunlight) effectively. To realize the useful chemical reactions, such as reduction of CO2by H2O, artificial Z-scheme is required similar to the natural system of photosynthesis of plants. We are challenging the construction of the system by hybridizing our metal complexes and semiconductors.
