Coupling of the water-splitting mechanism and doping-mixture method to design a novel Cr-perovskite for rapid and efficient solar thermochemical H₂ production

Abstract

The solar thermochemical water-splitting (STWS) via two-step redox reaction is a promising H2 production technique, but the quantity and performance limitation of perovskite materials motivate the discovery of novel high-performance...

Optimizing dense particles for efficient thermochemical fuel generation through a unified particle-level model

“…[10][11][12][13] Alternatively, perovskite-based materials usually feature favorable reduction thermodynamics due to their large d and fast reduction kinetics, whereas their oxidation kinetics are highly unfavorable, leading to limited fuel yields, which hinders their wide applications. [14][15][16] To date, various novel materials with promising intrinsic thermodynamics and kinetics have been reported, [17][18][19] where most research on thermochemical kinetic modeling is based on the rst-order model or Arrhenius expression. [20][21][22] By tting this type of expression with the experimental reaction rate curves, the optimal kinetic expressions are obtained for predicting the reaction rates at different temperatures and oxygen partial pressures.…”
