The Role of Fluorine in F-La/TiO(2) Photocatalysts on Photocatalytic Decomposition of Methanol-Water Solution

F-La/TiO(2) photocatalysts were studied in photocatalytic decomposition water-methanol solution. The structural, textural, optical, and electronic properties of F-La/TiO(2) photocatalysts were studied by combination of X-ray powder diffraction (XRD), nitrogen physisorption, Ultraviolet–visible diffu...

Descripción
Sumario:F-La/TiO(2) photocatalysts were studied in photocatalytic decomposition water-methanol solution. The structural, textural, optical, and electronic properties of F-La/TiO(2) photocatalysts were studied by combination of X-ray powder diffraction (XRD), nitrogen physisorption, Ultraviolet–visible diffuse reflectance spectroscopy (UV-Vis DRS), Electrochemical impedance spectroscopy (EIS), and X-ray fluorescence (XPS). The production of hydrogen in the presence of 2.8F-La/TiO(2) was nearly up to 3 times higher than in the presence of pure TiO(2). The photocatalytic performance of F-La/TiO(2) increased with increasing photocurrent response and conductivity originating from the higher amount of fluorine presented in the lattice of TiO(2).
