Nano Size Lanthanum Doped Semiconductors: Synthesis, Characterization and their Photocatalytic Activity
In the present study, La-doped TiO2 and ZnO nano particles were synthesized and extensively characterized by various sophisticated techniques such as XRD, nitrogen adsorption, UV-Vis, AFM and XPS. Rough and highly porous surface of La-doped photocatalysts was observed by AFM, which is critical for enhancing the photocatalytic activity. Degradation and mineralization studies of monocrotophos (MCP) revealed that 1 wt% La-doped TiO2/ZnO exhibits high activity compared to that of pure TiO2/ZnO.
