Preparation and Visible Light Photocatalytic Activity for Photocatalyst of Permeable Glass Membrane/TiO₂ Doped with Co

The photocatalyst of permeable glass membrane/TiO₂ doped with Co (permeable glass membrane/TiO₂ doped with Co) is prepared by the sol-gel method. The morphology and phase of the samples are determined by the field emission scanning electron microscopy (FESEM) and x-ray diffraction experiment, respectively. The photocatalytic results show that the photocatalyst is sensitive to the visible light and exhibits excellent photocatalytic activity of photodegradation methylene blue. The photocatalytic mechanism is also discussed.
