The facile synthesis of ZnO-graphene oxide nanohybrid and its photocatalytic application

A nanohybrid of Zinc oxide (ZnO)-graphene oxide (GO) is synthesized by chemical route and utilized as an effective photocatalyst for the photodegradation of crystal violet (Cv) dye. The substantially mixed ZnO-GO nanohybrid is formed by the introduction of GO during the synthesis of ZnO. The prepared ZnO-GO nanohybrid shows the better optical properties and exhibits the good interaction between GO and ZnO. The photocatalytic activity of ZnO-GO nanohybrid is analyzed by performing the photodegradation of Cv-dye under light illumination. Enormously high degradation of Cv-dye by ~95% within 80min is observed over the surface of advanced ZnO-GO nanohybrid, which might attribute to the presence of GO sheets as a supporting material and high ē-h⁺ pair separation under light illumination.
