Abstract
Photosynthesis in plants, algae and cyanobacteria uses light energy from the Sun to convert CO2 and water into carbohydrates and oxygen, thus sustaining all aerobic life forms on Earth. Photosynthetic water splitting into oxygen, protons and electrons, is catalyzed by the oxygen-evolving center (OEC) in photosystem II (PS II), which is crucial in global bioenergetics and has shaped the atmosphere by oxygen production. Due to the broad fundamental interests and potential applications in artificial photosynthesis, the structure and mechanism of this natural catalyst have attracted extensive attentions during the last two decades. Recent X-ray structure of PSII reported by Dr Shen’s group have revealed that OEC is comprised

Dr Zhang and his team have demonstrated that the artificial Mn4Ca-cluster might be able to serve as a potential catalyst for water-splitting reaction similar to the biological oxygen-evolving center (OEC)
To elucidate the catalytic properties of this artificial Mn4Ca-cluster, more investigations are required in future
Summary
Photosynthesis in plants, algae and cyanobacteria uses light energy from the Sun to convert CO2 and water into carbohydrates and oxygen, sustaining all aerobic life forms on Earth. After more than 18 years investigation on both natural photosynthesis and artificial photosynthesis, recently, Dr Zhang
