Progress in water oxidation catalysts

Abstract

Light-driven water splitting for the production of clean energy hydrogen is one of the most important solutions for alleviating energy crisis. However, the catalytic water oxidation to molecular oxygen is still the bottleneck of the entire process. This obviously limits their practical application in the water-splitting device. Recently, significant progress has been made in this field, in which well-defined molecules are opening up entirely new possibilities for the design of more rugged and efficient catalysts, with the hard work of scientists who are working on solving the worlds energy problem. In the present review, we summarize the recent progress in water oxidation catalysts, which is mainly divided into four sections: the selection of metals and ligands, effects of geometric structure, advantages of self-assemble.
