Catalytic removal of organic colorants from water using some transition metal oxide nanoparticles synthesized under sunlight
Transition metal oxides (TMO) constitute a most amazing class of materials with a wide
range of properties and applications; therefore, their synthesis using a green approach is a
necessity. As such, sunlight irradiation was employed to synthesize various TMO
nanostructures (ZnO, CuO, Co3O4, NiO and Cr2O3) using water as a solvent. Nanoparticles
obtained with distinct morphologies, such as nanotubes (ZnO;< 35 nm), nanorods (CuO; 7–
50 nm), nanorods, triangles and hexagons (Co3O4; 45–90 nm), needle-shaped (NiO; 2–25 …
