Abstract

Ag2O/GO/TiO2 composite nanoparticles were synthesized via a two-stage route including wet chemical and sol-gel techniques. The phase regarding the composition and morphology of composite nanoparticles was characterized using X-ray diffraction (XRD), Fourier transfer infrared (FT-IR) spectroscopy, and field emission scanning electron microscopy (FESEM). The structural studies revealed the successful formation of 300-nm Ag2O/GO/TiO2 composite spheres self-assembled to 35-nm particle aggregates. UV-Vis diffuse reflectance spectroscopy (DRS) was utilized to investigate optical properties. The results indicated an absorption edge in the UV region with a band-gap equivalent to 3.2 eV for Ag2O/GO/TiO2 composite nanoparticles. The morphological features of the sample were investigated with a Zeiss (EM10C, Germany) transmission electron microscope (TEM) operating at 100 kV.
