Abstract

For hydrogen production by water splitting, the water oxidation half reaction is overwhelmingly rate limiting and needs high over-voltage. This results in low conversion efficiencies when working at currently required densities. At such high voltage, other chemicals will be also oxidized.  This is environmentally unacceptable for large-scale H2 production.

Research on the synthesis of various metal compounds aimed at the simulating water oxidizing complex of Photosystem II has surged in recent years. Particular attention has been given to the manganese compounds because manganese is cheap and environmentally friendly. Authors review manganese compounds as functional models of the water oxidizing complex of Photosystem II for hydrogenproduction via water splitting.
