Thermodynamic Guiding Principles for Designing Nonstoichiometric Redox Materials for Solar Thermochemical Fuel Production: Ceria, Perovskites, and Beyond

Abstract

Two-step solar thermochemical water splitting is a promising pathway for renewable fuel production. Among the state-of-the-art materials, ceria tends to favor the oxidation step while perovskites favor the reduction step and developing a champion material with well-balanced redox thermodynamics remains a key challenge. A generic thermodynamic framework is thus presented to guide material design. More details can be found in article number 2000925, Wojciech Lipiński and co-workers.
