Synthesis and photocatalysis of ZnO/γ-Fe2O3 nanocomposite in degrading herbicide 2,4-dichlorophenoxyacetic acid

ZnO/γ-Fe2O3 catalysts were fabricated via a simple precipitation route using zinc acetate and iron acetate as the precursors and ammonia as the precipitant. The resulted nanocatalysts were subjected to heat treatment at 450°C for 2 h. The characteristics of the nanocomposite were investigated by var...
