Abstract
The main objective of this study was to chemically synthesize Bi doped ZnO nanoparticles and explore their potential for environmental and biomedical applications. In this research, Bi doped ZnO nanoparticles were synthesized through soft chemical precipitation route and investigated their structural, morphological, Raman, optical, photocatalytic, and antibacterial characteristics. Structural and morphological studies revealed the formation of spherically shaped Bi doped ZnO nanoparticles with single phase hexagonal wurtzite structure. Bi doping led to widened optical band gap of ZnO nanoparticles due to Burstein-Moss shift. Photocatalytic degradation efficiency towards MB dye was increased from 51 to 68% under natural sunlight irradiation. The antibacterial activity of ZnO nanoparticles was also observed to be enhanced significantly with Bi doping due to decrement in average particle size and enhanced reactive oxygen species (ROS) production. It was observed that Bi doped ZnO nanoparticles may be better choice for degradation of organic dyes and antibacterial applications comparing pristine ZnO.
