From: Giant onsite electronic entropy enhances the performance of ceria for water splitting

Calculated \({\rm{\Delta}}S_{{\rm{elec}}}^{{\rm{onsite}}}\) for lanthanides ions. Predicted electronic entropy of reduction per oxygen vacancy for the lanthanide oxides studied in this work. At high temperature, reduction of CeO2 has the highest \(\Delta S_{{\rm{elec}}}^{{\rm{onsite}}}\) followed by reduction of TbO2 (see Table 1)
