Abstract
Phosphorus and cobalt codoped TiO2 nanomaterial was successfully prepared by single step sol-gel method by doping different weight percentages of dopants concentrations into TiO2 lattice. The co-doped TiO2 samples were characterized to confirm the structural and morphological changes in TiO2 crystal lattice by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), transmission electron microscopy (TEM), UV-visible diffuse reflectance spectroscopy (UV-vis. DRS), X-ray photo electron spectroscopy (XPS), Brunauer-Emmmett-Teller surface area analyzer (BET) and Fourier transform infrared spectroscopy (FT-IR). The characterization results revealed that all the codoped samples show anatase phase, nanoparticle (5.8 nm) and narrow band gap (2.54 eV). These results enhance the photocatylytic activity of codoped TiO2 in visible light for the degradation of Fast Green dye within 60 min.
