Multimorphologies nano-ZnO preparing through a simple solvothermal method for photocatalytic application

A simple solvothermal method to successfully synthesize multimorphologies nano-ZnOs. The effect of diethylenetriamine on controlling the morphology of ZnO was studied by scanning electron microscopy (SEM). It is demonstrated that diethylenetriamine has significant influence on the two-dimension length of ZnO. Photocatalytic activities of as-prepared multimorphologies nano-ZnOs were also valuated using methyl orange as a model pollutant. The results show multimorphologies nano-ZnOs to have excellent photocatalytic activity.
