Synthesis of Pure Brookite Nanorods in a Nonaqueous Growth Environment

Mohammad Khaja Nazeeruddin, Mahmoud Saeed Qaid Mohammad Hezam

Brookite TiO2 is the most difficult TiO2 polymorph to synthesize. The available methods in the literature to produce brookite nanostructures mostly use water-based techniques for the preparation of water-soluble Ti complexes first, followed by a hydrotherm ...

Synthesis and characterization of fluorinated anatase nanoparticles and subsequent N-doping for efficient visible light activated photocatalysis

Paul Bowen, Sami Rtimi

Fluorinated-titanium dioxide (TiO2-F) nanoparticles in a pure anatase polymorph was precipitated from solution by hydrolysis of titanium oxychloride, using urea and ammonia as precipitation agents and potassium fluoride as a source of fluorine anion. A fur ...

Electron Kinetics in Dye Sensitized Solar Cells Employing Anatase with (101) and (001) Facets

Michael Graetzel, Mohammad Khaja Nazeeruddin, Pascal Comte, Ladislav Kavan, Thomas Moehl, Aswani Yella

Two phase-pure nanocrystalline anatase materials differing in the exposed crystal facets (001) or (101) are studied by electrochemical impedance spectroscopy and by transient photovoltage and photocurrent decay in dye sensitized solar cells. A larger chemi ...

Synthesis of poly(methacrylic acid) brushes via surface-initiated atom transfer radical polymerization of sodium methacrylate and their use as substrates for the mineralization of calcium carbonate

Harm-Anton Klok, Stefano Tugulu, Raphaël Barbey

This manuscript describes the synthesis of poly(methacrylic acid) (PMAA) brushes via surface-initiated atom transfer radical polymerization (SI-ATRP) of sodium methacrylate (NaMA) and their use as substrates for the mineralization of calcium carbonate. A C ...
