| Environmental threat due to the pollution of water bodies by organic dyes, which can lead to the creation of a colored layer on the surface waters and prevent the penetration of sunlight into the waters, and ultimately disrupt the life of microorganisms. In addition to all this, due to their high toxicity, it has become a serious concern for the health of humans and animals. Recently, innovative treatments based on nanotechnology for wastewater treatment processes are increasing. In this study, a simple and safe method was reported for the efficient degradation of four organic dyes (bromothymol blue, eriochrome black T, methyl red and bromocrosol green) using Bi-doped ZnO nanoparticles under sunlight. Based on the performed experiments, the Bi-doped ZnO photocatalytic activity was better than the single ZnO semiconductor. The present study can be considered as an effective step towards the photocatalytic treatment of wastewater to remove dyes using sunlight as a renewable source of energy. | ||
