Effects of Mn on the magnetic and optical properties and photocatalytic activities of NiO nanoparticles synthesized via the simple precipitation process

Highlights
- Pure and Mn doped NiO were synthesized via very simple precipitation method.
- Mn concentrations played a vital role to modify the properties of NiO.
- Quantum confinement effect was occurred in the UV-vis spectra due to lower size.
- MeO dye was degraded up to 84.43% by Mn doped NiO compared with pure 63.63%.
- Proposed method has the important advantage of being simple, fast and cost effective.
