This work presents the results of the structural characterization of LaSrGa1-xMgxO4-δ oxides with x=0.0-0.2 (LSGM'); these oxides with layered K2NiF4-type structure are potential electrolytes of oxygen ions with applications in...
Triethylphosphine oxide [(C2H5)3PO; TEPO] was intercalated into protonated Dion–Jacobson-type ion-exchangeable layered perovskites, HLaNb2O7·xH2O and HCa2Nb3O10·xH2O, by hydrolysis of their n-decoxy derivatives in the presence of TEPO.
