摘要：
The present work studies the photocatalytic degradation of Cr-doped ZnO nanoparticles toward aqueous mixture of organic dyes, such as methyl orange, methylene blue and congo red. Cr-doped ZnO nanoparticles were synthesized using co-precipitation method and characterized by several method of measurements. Photocatalytic mechanism was investigated by measuring the photocatalytic degradation rate in the presence of scavenger. The results revealed that hydroxyl radical plays an important role in photocatalytic activity.
