Abstract

We report ternary AgI–FG–TiO2 nanocomposites prepared through fast microwave technique. In this study we introduced a novel chemical vapor deposition (CVD) approach to functionalize powder graphene oxide (GO). The functionalize graphene (FG) sheets were then used for the attachment of AgI and TiO2 nanoparticles to form a ternary composites. The prepared composites were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopic analysis, X-ray diffraction (XRD), UV–vis absorbance spectra and UV–vis diffuse reflectance spectra (DRS). The photocatalytic activity for hydrogen evolution was greatly affected by the introduction of FG and ternary component in the system.
