“…Interestingly, previous experimental studies in the literature generally agreed in assigning the 2163-2164 cm -1 band to the CO/(001) system. 19,20 However, our results suggest that at high CO coverage: -the regular (001) facets should not contribute to signals characterized by wavenumbers higher than 2134 cm -1 (ESI , Table S2c); -only CO adsorbed on reconstructed (001) surfaces [the (1x4) reconstruction is well known to occur for this type of surface 66,67 ] might contribute (at the tail) to the 2160-2150 cm -1 region.…”

Integrated studies of CO on truncated bipyramidal TiO 2 anatase nanoparticles mainly exposing smooth (101) surfaces provide the missing link between TiO 2 single crystals and commercial TiO 2 nanopowders with complex morphology. The synergy among high resolution transmission electron microscopy, IR spectroscopy and modeling correlates adsorbed CO stretching frequency to anatase surface type, and reveals how disorder of the adsorbed CO layer affects CO/TiO 2 IR bands.

“…All TiO 2 single crystal surfaces exhibit sharp LEED patterns with the dotted rectangular indicating the reciprocal unit cell. Agreeing with previous reports, [27][28][29] the LEED pattern of clean TiO 2 A-(001) surface exhibits two domains corresponding to (1×4) and (4×1) reconstructions respectively in the [100] and [010] directions, and the resulting TiO 2 A-(001)-(1×4) surface exposes the fourfold-coordinated Ti atoms (Ti 4c ) at the ridge, the fivefold-coordinated Ti atoms (Ti 5c ) at the terrace and the twofold-coordinated O atoms (O 2c ). The clean TiO 2 R-(110) surface does not reconstruct and exposes alternating rows of Ti 5c and O 2c atoms.…”

“…surfaces could be attributed to the fact that the rutile TiO 2 surfaces are more easily reduced than the anatase surfaces and thus exhibit a better conductivity. [28] Thus it is likely that the A-(001)-(1×4) surface suffers from the charging effect during the XPS measurement. Figure 3 compares the TDS spectra of methanol adsorption on various clean TiO 2 single crystal surfaces at 115 K. Only the methanol desorption trace was observed for all surfaces.…”

Structural Dependence of Competitive Adsorption of Water and Methanol on TiO₂ Surfaces

Employing TiO 2 anatase (001)-(1×4), rutile (110) and rutile (011)-(2×1) single crystal surfaces, we comprehensively studied the effects of TiO 2 surface structures on the competitive adsorption of water and methanol by means of low energy electron diffraction, thermal desorption spectra and X-ray photoelectron spectroscopy. The relative adsorption strengths of chemisorbed methanol and water vary with the TiO 2 surface structures and the adsorption sites. This leads to TiO 2 surface structure-dependent competitive adsorption of water and methanol. The chemisorption of CH 3 OH on TiO 2 anatase (001)-(1×4) surface is seldom affected by pre-covered water at low coverages but is affected by pre-covered water at high coverages; the chemisorption of CH 3 OH on TiO 2 rutile (110) surface is seldom affected by pre-covered water; and the chemisorption of CH 3 OH on TiO 2 rutile (011)-(2×1) surface is affected by pre-covered water even at low coverages. These results deepen the fundamental understandings of surface chemistry on TiO 2 surfaces.

“…Under identical optimized MBE growth conditions, whether anatase or rutile nucleates depends entirely on the substrate; rutile (100) forms on a-Al 2 O 3 (001) whereas anatase (001) nucleates on SrTiO 3 (001), LaAlO 3 (001), and other perovskite substrates. [99,100,[203][204][205][206][207][208][209][210][211][212] In all cases, there are twodimensional symmetry matches between substrate and film in the growth plane, and some similarity in the in-plane lattice parameters. As expected, rutile also exclusively nucleates on rutile (110), (001), and (100) substrates.…”

Epitaxial Growth and Properties of Doped Transition Metal and Complex Oxide Films

The detailed science and technology of crystalline oxide film growth using vacuum methods is reviewed and discussed with an eye toward gaining fundamental insights into the relationships between growth process and parameters, film and interface structure and composition, and electronic, magnetic and photochemical properties. The topic is approached first from a comparative point of view based on the most widely used growth methods, and then on the basis of specific material systems that have generated very high levels of interest. Emphasis is placed on the wide diversity of structural, electronic, optical and magnetic properties exhibited by oxides, and the fascinating results that this diversity of properties can produce when combined with the degrees of freedom afforded by heteroepitaxy.
