Synthesize of Tri-Metal Oxide MnO-ZnO-CeO Nanocomposites via Co-Precipitation Technique for Biomedical and Environmental Applications.

Tri-metallic MnO-ZnO-CeO nanocomposites were successfully synthesized via a co-precipitation method. Structural characterization confirmed the formation of orthorhombic MnO, hexagonal ZnO, and cubic CeO phases, with an average crystallite size of approximately 18 nm. The nanocomposites exhibited a narrow band gap of 2.

Investigations on Chemically Synthesized Pure and Doped Manganese Dioxide Nanoparticles for Dye Removal and Photocatalytic Applications.

Pure and Mg, Ni, Cd doped MnO nanoparticles were synthesized by chemical co-precipitation method. These samples were characterised by PXRD, SEM, EDX, FTIR, UV-Vis-NIR, PL, Antibacterial, Cyclic Voltammetry, Dye Degradation and Photocatalytic studies. From the powder XRD studies, the crystallite size of the particle was calculated using Scherer formula and found that the synthesized nanoparticles were in the range from 10 to 12 nm.
