A clean and efficient process for producing hydrogen using renewable energy sources is an important requirement for a future Hydrogen Economy. The production of hydrogen from water and solar energy is attracting widespread attention. In particular, research is focused on novel materials, or improving existing materials for the splitting of water using photocatalysis and photoelectrolysis. In this paper we highlight several recent developments in photocatalysts and we illustrate how engineering of properties on an atomic scale can be achieved by cation and anion doping, deviations from stoichiometry and in case of ternary or more complex materials, by deviations from molecularity. The defect chemistry of I‐III‐VI 2 ternary semiconductors with the chalcopyrite structure is presented and used to construct a 3D‐Brouwer diagram.
