“…The shape of ZnO nanostructures also plays a major role in determining their physical properties and photocatalytic performance for environmental applications [18,19]. However, it is well known that erosion of ZnO structures takes place when they are exposed to water, especially water with extreme PH values [20][21][22]. Therefore, in the field of environmental application and, specifically, water pollutants removal, the stability of the ZnO photocatalysts and their erosion resistance are of great importance in terms of their durability, as well as their economic feasibility for treating contaminated water.…”

“…Therefore, in the field of environmental application and, specifically, water pollutants removal, the stability of the ZnO photocatalysts and their erosion resistance are of great importance in terms of their durability, as well as their economic feasibility for treating contaminated water. Various studies have reported the effect of erosion on ZnO structures for growth orientation and structures transformation in water-splitting and in water-treatment applications [20][21][22][23][24][25][26][27]. Additionally, some previous studies have reported that ZnO shows good thermodynamic stability in aqueous solutions in the high pH range from 8 to 13 [28].…”

ZnO nanostructured materials have been widely utilized in several environmental depollution applications. In the current work, ZnO nanorods were grown using the electrodeposition method with different precursor concentrations. A variation in the dimensions of the nanorods grown with the different precursor concentrations was noticed, as expected. The ability of the fabricated nanorods to remove water pollutants under UV irradiation and their photocatalytic performance stability was also evaluated over a prolonged period of time. Interestingly, the samples grown in different conditions exhibited different capabilities to maintain their morphology and their photocatalytic performance after they were kept in contaminated water for a long time. Moreover, some samples also were found to remain photocatalytically active for approximately 47% longer than other samples. These findings indicate that the performance stability of ZnO nanorods for pollutants removal and their robustness can be greatly improved by controlling their growth parameters, which will favorably impact the use of ZnO nanorods for water-treatment applications and their economic aspects.
