In this study, we fabricate Ti4+ doped WO3 hybrid composites and successfully anchor it onto reduced 3-methanyltrimethoxysilane modified graphene oxide for Ti4+/WO3@GO-NH2 photocatalysts. The structural, morphological, and photochemical properties of the obtained samples were thoroughly investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), N2 adsorption/desorption, UV-vis diffuse reflectance (UV-vis DRS), thermogravimetric-differential thermal analysis (TG-DTA), and Raman spectroscopy. And the photocatalysts could decompose rhodamine B dye under visible-light and exhibited higher activities than pristine materials. The excellent adsorption capacity and good reusability properties of the (Ti4+/WO3@GO-NH2 suggest that it can be applied as novel adsorbents showing attractive commercial value.
