Abstract

Reduced graphene oxide-ZnO (72/0، 36/0، 18/0= GO/Zn(Ac)) was synthesized using GO and Zn(Ac) by a chemical bath root. The optical properties were performed by FTIR and DRS spectroscopies and the structural properties by XRD, SEM and EDS observations. The DRS spectra of rGO-ZnO show an absorption edge at about 389 nm. The vibration modes related to ZnO bonds and also reduction of GO were observed by FTIR spectra. The XRD, EDS and SEM results showed that ZnO was formed in a hexagonal structure on the rGO surfaces. The toxicity of the prepared samples was studied on (N2A) cellulose. It was shown that GO and rGO-ZnO with 0.18 and 0.36 GO/Zn(Ac) ratio have similar toxicity behaviors in higher concentration compared to the 0.72 which shows toxicity in lower concentrations.
