Evaluation of applicability of Nd- and Sm-substituted Y1-xRxMnO3+δ in temperature swing absorption for energy-related technologies

An attempt is undertaken to chemically modify YMnO3+δ by the partial substitution of Y with larger Nd and Sm, aiming to boost the oxygen storage performance in the temperature swing process. Single-phase (P63cm) Y0.95Nd0.05MnO3+δ and Y0.95Sm0.05MnO3+δ compounds are obtained in a sol-gel auto-combust...
