Removal of organic dye from aqueous solution using nano zero valent zinc-zinc oxide

In recent years, the uses of zero-valent metal such as Fe, Zn and etc., for the treatment of toxic chemicals in waters have received wide attention [1]. In this work, simultaneous synthesis of nano zero-valent zinc (reductive catalyst) on ZnO (as a photocatalyst) was done. The results showed the photocatalytic activity of prepared photocatalyst compared with nanosized ZnO as a standard photocatalyst was increased in same operational condition
