AgBr nanoparticles-ZnO flowers nanocomposites used for photodegradation of methylene blue solution illuminated by ultraviolet-visible radiation

Different weight contents of AgBr nanoparticles supported on hierarchical ZnO nanostructure flowers were synthesized by precipitation-deposition method at room temperature. The nanocomposites were investigated for photocatalytic degradation of methylene blue (MB) under ultraviolet (UV)-visible light irradiation. The analytical results show that AgBr nanoparticles with size range of 60-80 nm were supported on hierarchical ZnO nanostructure flowers with similar to 4 mu m diameter. The photodegradation was improved by AgBr nanoparticles loaded on ZnO nanopetals. In this research, 10 wt% AgBr-ZnO nanocomposites have the highest photodegradation of MB under UV-visible light irradiation.

Automated summary

AgBr nanoparticles supported on hierarchical ZnO nanostructure flowers were found to enhance the photocatalytic degradation of methylene blue. Among the composites studied, the 10 wt% AgBr-ZnO nanocomposites demonstrated the highest photodegradation efficiency under UV-visible light irradiation.
