Abstract

In this paper we intend to give a broad overview of natural and artificial photosynthesis systems. We point out seven orders of magnitude difference of the rates of water splitting between natural and state of the art artificial photosynthesis in favour of natural photosynthesis. We reviewed the open literature for photocatalytic water splitting, CO2 reduction and suggested routes for improvements in the low yields.
