We combined scanning tunneling microscopy and x-ray photoelectron spectroscopy
experiments with density-functional theory calculations to study dispersed tungsta clusters
on anatase Ti O 2 (101). Following two different preparation methods, we found that
monomeric WO 3 species are the most stable configuration rather than WO 3 trimers,(WO 3)
3. The WO 3 monomers form tetrahedral WO 4 structures on anatase Ti O 2 (101), with one
W–O bond and two W–O–Ti linkages per WO 3 monomer. Locally, the WO 3 monomers form …

We combined scanning tunneling microscopy and x-ray photoelectron spectroscopy experiments with density-functional theory calculations to study dispersed tungsta clusters on anatase . Following two different preparation methods, we found that monomeric species are the most stable configuration rather than trimers, . The monomers form tetrahedral structures on anatase , with one W–O bond and two W–O–Ti linkages per monomer. Locally, the monomers form well-ordered (2 × 1) structures. The discovered geometric structure of on anatase opens up numerous opportunities for fundamental studies addressing tungsta and accurate structure-activity studies of model catalysts.
