Abstract

Production of clean energy in a sustainable way is of utmost importance in modern society, but reactions such as the oxygen evolution reaction, well-known for its sluggishness and energy requirements, play a key role in fuel cells technology and conversion of solar energy into fuels. Thus, efficient water oxidation catalysts (WOCs) based on abundant elements are attracting lots of scientific and technological interest, where active site engineering and a conductivity optimization approach are being used in the quest for the "ideal catalyst." The recent advancements in the design of molecular and oxide/hydroxide WOCs, as well as hybrid derivatives and composite materials are the scope of this chapter. The choices and tuning of relevant structural and electronic parameters are fundamental for molecular and hybrid materials, and the isomorphic substitution in, and doping of bimetallic and trimetallic oxide/hydroxides, are paving the way to high performance WOCs.
