Photocatalytic efficiency of green synthesized ZnO nanoparticles for the degradation of methyl orange dye: A review

The primary global source of water pollution is industrial and textile dyes. These industries produce Highly stable organic dyes that are released untreated into nearby ponds, lakes rivers. As ZnO nanoparticles (NPs) inexpensive, non-toxic, chemically thermally stable, have a higher UV absorption capacity, they an effective nano-catalyst for removing hazardous contaminants such as inorganic from wastewater. green synthesis synthesised NPs, their shape size, photocatalytic effectiveness against the dye methyl orange all described in this paper. emphasis on environmentally friendly NPs using plant extracts because process impacts characteristics applications NPs. Additionally, based recently published literature, size factors affect activity degradation MO highlighted.
