Fabrication of TiO/NiO p-n Nanocomposite for Enhancement Dye Photodegradation under Solar Radiation.

A p-n nanocomposite based on TiO nanotubes (NTs) and NiO nanoparticles (NPs) was designed and optimized in this study to improve the photocatalytic performance of methylene blue (MB). The hydrothermal technique has been used to produce TiO/NiO nanocomposites with different NiO NPs weight ratios; 1TiO:1NiO, 1TiO:2NiO, and 1TiO:3NiO. The crystal phase, chemical composition, optical properties, and morphology of TiO/NiO were explored by various techniques.
