Water Splitting Technology STCH

Status Awarded

Abstract The current proposal aims to contribute to materials discovery for improved solar thermochemical water-splitting materials, through fundamental quantum mechanics investigations into an exciting class of redox active, mixed ionic electronic conducting metal oxides, which can stably exist over a range of oxygen stoichiometries. By characterizing key thermodynamic properties and stability, we aim to offer strategies to boost solar to hydrogen thermal efficiency, as well as to provide experimentalists with crucial input to synthesize, validate, and perform further tests on promising candidates.
