The mechanisms of water oxidation in artificial photosynthesis

Leave a Comment / Artificial Photosynthesis / By

Artificial photosynthesis involves several mechanisms of water oxidation. Generally, the operating mechanisms in the formation of oxygen-oxygen bonds are different. The first mechanism is the water nucleophilic attack (WNA) and the second mechanism is the interaction between two metal-oxygen (M-O) entities. In WNA, a molecule of water from the solvent attacks an oxo group from …

Light-harvesting system component in artificial photosynthesis

Leave a Comment / Artificial Photosynthesis / By

An artificial photosynthesis system, which mimics the natural photosynthesis system, comprises of three units. The first is a light-harvesting unit. The second is a charge separation unit (reaction center). The third is a catalysis unit where fuel-forming multi-electron reactions take place. This article discusses the light-harvesting system. The chromophore (photosynthesizer) Light harvesting is the initial …
