Abstract
Amine functionalized graphene oxide (NH2-GO) decorated with ZnO-ZnFe2O4 nanomaterials (NH2-GO/ZnO-ZnFe2O4) was successfully synthesized by organic transformation reaction followed by hydrothermal method. The formation, composition, bonding, size, morphology, and surface area of synthesized nanomaterial were analyzed by XRD, FTIR, Raman, XPS, FESEM, HRTEM, and BET analytical techniques. The formation of ZnO-ZnFe2O4 binary phase onto the amine functionalized GO was confirmed by XRD and HRTEM. The surface composition and functionalization of prepared nanocomposite were confirmed by XPS and FTIR analysis. The FESEM images revealed the formation of fine spherical ZnO-ZnFe2O4 nanoparticle onto the NH2-GO surface. From TEM image, the average particle size of the composite nanomaterials was observed to be 8 nm. From N2 adsorption–desorption study, it was found that NH2-GO/ZnO-ZnFe2O4 composite nanomaterials show higher surface area (122 mg/g) than GO/ZnO-ZnFe2O4 and NH2-GO. The obtained nanocomposite was used as ...
