Structure-efficacy relationship of sphere (sZnO), ellipsoid (eZnO), short rod (srZnO), long rod (lrZnO), cubic (cZnO), urchin-like (uZnO), and platelet-like ZnO (pZnO) materials toward photocatalysis. (A) General mechanism of the photocatalysis on ZnO particle. (B) Photocatalysis degradation kinetics of MB and RB using uZnO under UV lamp (30 W/m2) and Tungsten halogen lamp (80 W/m2) treatment. C0 is the initial concentration of MB and RB dye solution, while C represents the remaining dye concentration of MB and RB after that time interval. (C) The reusability test of uZnO in the photodegradation of MB. (D) The structure effect of ZnO on the photocatalysis of MB and RB under UV lamp (30 W/m2) and Tungsten halogen lamp treatment (80 W/m2).
