Abstract :
The photocatalytic degradation of rhodamine B (RB) was studied by using ZnO nanorods as the catalyst under UV light irradiation. The effect of the RB concentration and ZnO catalyst dosage were investigated. The degradation rate reaches maximum when the pH value is about 11. The reuse of the as-grown ZnO catalysts has little effect on their photocatalytic activity.
