  2. 21. Aqueous Exfoliation of Transition Metal Oxides for Energy Storage and Photocatalysis Applications : Vanadium Oxide and Molybdenum Oxide Nanosheets

    Author : Ahmed S. Etman; Junliang Sun; Yury Gogotsi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aqueous exfoliation; vanadium oxide nanosheets; molybdenum oxide nanosheets; energy storage; photocatalysis; Inorganic Chemistry; oorganisk kemi;

    Abstract : Two-dimensional (2D) transition metal oxides (TMOs) are a category of materials which have unique physical and chemical properties compared to their bulk counterparts. However, the synthesis of 2D TMOs commonly includes the use of environmental threats such as organic solvents. READ MORE

  4. 22. Mesoporous Titania for High Rate Electrochemical Energy Storage

    Author : Giulio Calcagno; Chalmers tekniska högskola; []
