| titleOfInvention | Flower-shaped ZnO photocatalyst of Ce doping applied to dye wastewater treatment and preparation method thereof |
| abstract | The present invention relates to flower-shaped ZnO photocatalyst of the doping of the Ce applied to dye wastewater treatment and preparation method thereof.There is the defects such as low, the light induced electron recombination rate height of utilization rate of visible ray, limit the light-catalysed performances of ZnO in ZnO as a kind of photochemical catalyst.The present invention is using sodium hydroxide as alkali source, zinc nitrate hexahydrate is originated for ZnO crystal seed, lauryl sodium sulfate is dispersant, six nitric hydrate ceriums are dopant, the mixed liquor of second alcohol and water is solvent, and the appearance of ZnO prepared through mechanical agitation, ultrasound, the synthesis of microwave radiation technology hydro-thermal method, centrifugation, drying and other steps is flower-like structure.Photocatalytic degradation experiment shows that introducing hetero-atoms Ce can effectively suppress light induced electron and photohole inside ZnO into ZnO lattice structures（e ‑ /h + ）It is compound, widen ZnO spectral response range, this provides practicable reference frame for improving nano-ZnO photocatalysis to the utilization ratio of visible ray. |
