En route to artificial photosynthesis: the role of polyoxometalate based photocatalysts

Abhik Paul et al.

Summary: Artificial photosynthesis is crucial for providing renewable energy resources due to increasing global energy demand and depleting fossil fuels. Constructing an ideal artificial photosynthetic system requires essential components such as photosensitizer, water oxidation catalyst, and CO2 reduction catalyst. Dividing the overall process into two half-reactions and utilizing polyoxometalates (POMs) to reduce activation energy barriers play key roles in enhancing the efficiency of converting solar energy.
