Monodispersed nanorod-shaped Mn-Co co-doped ZnO nanoparticles for enhanced photocatalytic and antibacterial activities

The present work deals with synthesizing the pure ZnO (PZ), manganese-doped ZnO (MZ), and manganese-cobalt co-doped ZnO (MCZ) nanoparticles by hydrothermal method. X-ray diffraction confirms their hexagonal wurtzite structure with varying crystallite sizes: 43.8 nm for PZ, 34.6 nm for MZ, and 27.6 n...
