Structure and magneto-electric properties of hydrothermally prepared nanocrystalline GaxFe2−xO3 (x = 0.7, 1 & 1.3)

Origin of the Improved Photoelectrochemical and Photocatalytic Activity in a ZnO-TiO2 Nanohybrid Revealed by Experimental and Density Functional Theory Studies

“…Likewise, the TEM images of the ZnO-TiO 2 heterojunction in panels d and e of Figure and the inset of panel d show that spherical particles are uniformly embedded over ZnO nanorods, which could be due to the electrostatic interaction between the positively charged ZnO nanorods and negatively charged TiO 2 particles. The morphology of the constituent particles of the heterojunction remained unchanged even after the formation of the heterojunction due to the simple electrostatic self-assembly process, which does not require harsh reaction conditions to obtain the heterojunction as reported in other studies . The TiO 2 particles aggregated little and occupied the ZnO surface uniformly, while they still appeared spherical and rod-shaped individually.…”
