Abstract EN
ZnO nanowhiskers were used for photodecomposition of methylene blue in aqueous solution under UV irradiation.
The rate of methylene blue degradation increased linearly with time of UV irradiation.
54% of degradation rate was observed when the ZnO nanowhiskers were used as photocatalysts for methylene blue degradation for 80 min under UV irradiation.
The decoration of p-type NiO nanoparticles on n-type ZnO nanowhiskers significantly enhanced photocatalytic activity and reached 72% degradation rate of methylene blue by using the same method.
NiO-decorated ZnO was recycled for second test and shows 66% degradation from maximal peak of methylene blue within the same period.
The increment of photocatalytic activity of NiO-decorated ZnO nanowhiskers was explained by the extension of the electron depletion layer due to the formation of nanoscale p-n junctions between p-type NiO and n-type ZnO.
Hence, these products provide new alternative proficient photocatalysts for wastewater treatment.
