Nanostructure manganese oxide shows very good catalytic activity in waste water treatment of dyeing industry. A few nano manganese oxides are prepared through different methods, Their catalytic degradation property of dyeing material (crystal violet solution) is tested with H2O2 as oxidizer. Besides, the influence of other parameters are also studied, including catalyst dosage, H2O2 dosage and catalyst circulation. After reaction of 60 minutes, degradation of crystal violet can reach over 99% for most catalyst samples.
