Abstract:
This study describes the microwave assisted synthesis of without and with sodium hexametaphosphate (SHMP) (1 mol%) capped 3 mol% Ni- doped ZnO nanoparticles. Various sophisticated analytical techniques were used to characterize the Ni-doped ZnO nanoparticles. The results showed that including SHMP capped 3 mol% Ni-doped ZnO nanoparticles has a significant influence on the photoctalyst and structural characteristics of the ZnO nanoparticles. Under visible light illumination, SHMP capped 3 mol% Ni-doped ZnO nanoparticles demonstrated better photocatalytic degradation of methylene blue dye. As a

Morphological investigation as well as electrical conductivity of the undoped and Ni-doped ZnO NWLs was also discussed. The surface roughness of the formed ZnO NWLs was reduced after Ni-doping. The pore size of Ni-doped ZnO NWLs can be controlled by changing the concentration of hexamethylenetetramine (HMT). As the HMT concentration increased, the pores became larger with increasing surface roughness. The electrical conductivity of the electron-only device based on the
