Chemical approaches to artificial photosynthesis
TL;DR: In the early 1970s, the works by Fujishima and Honda (1) and Honda et al. (2) reported on the results of a now famous experiment that showed that band gap excitation of anatase TiO2 in a photoelectrochemical cell with a Pt counter electrode and an applied bias resulted in water splitting into hydrogen and oxygen.

Architecture of the Photosynthetic Oxygen-Evolving Center
TL;DR: The data strongly suggest that the OEC contains a cubane-like Mn3CaO4 cluster linked to a fourth Mn by a mono-μ-oxo bridge, and the details of the surrounding coordination sphere of the metal cluster and the implications for a possible oxygen-evolving mechanism are discussed.

Artificial Photosynthesis: Solar Splitting of Water to Hydrogen and Oxygen
Allen J. Bard,Marye Anne Fox +1 more
TL;DR: In this article, the authors focus on the photodriven conversion of liquid water to gaseous hydrogen and oxygen, a process similar to that of biological photosynthesis, using sunlight to drive a thermodynamically uphill reaction of an abundant material to produce fuel.
