Review on Recent Advances in Titanium Dye Oxide Nanoparticles for Dye Sensitized Solar Cell Applications.

“…Res. 5(4), 76-85 77 large advances in the fabrication, characterization, and fundamental understanding of TiO 2 nanomaterials in the past decade [1][2][3][4][5][6][7][8][9]. Dye-sensitized Solar Cells (DSSCs) are promising devices for inexpensive, large-scale solar energy conversion.…”

Methanol Conversion into Dimethyl Ether on the Anatase TiO2(001) Surface

“…[5,6] Thephotocatalytic conversion of methanol over TiO 2 has been ah ot topic in photocatalysis. [7] These reports have motivated fundamental studies of methanol adsorption and reaction on TiO 2 surfaces that mostly employed TiO 2 single crystals as amodel surfaces. [8][9][10][11][12][13][14][15][16][17][18] Among various types of TiO 2 facets anatase TiO 2 (001) is of particular interest.…”

Ability ofTiO2(110)surface to be fully hydroxylated and fully reduced

“…The majority of fundamental research of hydrogen on TiO 2 has been carried out on the model rutile (110)-(1 × 1) surface [1,10,11]. However, while behavior of single, isolated OH species on TiO 2 (110) has been intensively studied and relatively well understood [1,10], there were just a few attempts to prepare and examine surfaces hydroxylated close to saturation [12][13][14].…”
