    Sulfated Ce‐doped TiO2 as visible light driven

    Sulfated Ce‐doped TiO 2 photocatalysts improve the photocatalytic response of TiO 2 to visible light and the presence of Ce 4 /Ce 3 redox process facilitates the separation of photo‐generated electrons and holes. In addition the impregnation can create Lewis acid sites on the obtained catalyst surface. (O ad) and consequently

    Magnetite is a rock mineral and one of the main iron ores with the chemical formula Fe 3 O 4 is one of the oxides of iron and is ferrimagnetic it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite called lodestone will attract small pieces

    Review on Modified TiO2 Photocatalysis under UV/Visible

    Titania is one of the most widely used benchmark standard photocatalysts in the field of environmental applications. However the large band gap of titania and massive recombination of photogenerated charge carriers limit its overall photocatalytic efficiency. The former can be overcome by modifying the electronic band structure of titania including various strategies like coupling with a
