The photosynthesis of solar fuels from abundant raw materials is considered one of the most promising strategies to sustain the increasing worldwide level of energy consumption of our society . Inspiration for constructing an efficient photosynthetic apparatus has traditionally derived from Nature, who has developed two catalytic pools that offer viable kinetic pathways to both the oxidation of water (oxygen evolving complex) and generation of NAD(P)H [NAD(P)+ ferredoxin reductase]; NAD(P)H is successively used to reduce CO2 in light-independent reactions.
Many organometallic complexes have been successfully exploited to independently catalyze water oxidation (WO) , hydrogenation of NAD+, and dehydrogenation of NADH . In this contribution, our results aimed at developing homogeneous  and heterogenized  WOCs, as well as single organoiridium complexes, which can efficiently catalyze both WO and NAD+/NADH transformations, are reported (Figure 1).
