Nanorods like microstructure, photocatalytic activity and ac-electrical properties of (1-x) (Al0.2La0.8TiO3) + (x) (BaTiO3) (x = 0.2, 0.4, 0.6 & 0.8) nanocomposites.

TEM pictures of ALTBT nanocomposites. • ALTBT nanocomposites were synthesized via low temperature hydrothermal method. • x = 0.2 & 0.4 showed tetragonal phases and x = 0.6 & 0.8 showed the cubic phases. • The microstructure results indicated the formation of nanorods for all composites. • Cole-Cole plots of x = 0.2, 0.6 & 0.8 composites showed the increasing spring model. Nanorods like (1-x) (Al 0.2 La 0.8 TiO 3) + (x) (BaTiO 3) (x = 0.2–0.8) composites were synthesized via hydrothermal technique. The XRD patterns indicated that tetragonal to cubic phase transformation was occurred from x = 0.4 to 0.6. The surface morphology revealed that the x = 0.2–0.8 exhibited the nanorods like structures. The photocatalytic activity was noticed for all nanocomposites during irradiation time from 0 to 150 min. In addition, the increasing spring model Cole-Cole plots were recorded for x = 0.2, 0.6 and 0.8 composites at high temperatures. The grain and grain boundary contribution in electrical conduction mechanism was described. [ABSTRACT FROM AUTHOR]
