Can amine ligands atomically disperse Cu atoms on TiO2(110)? Cu deposition on TiO2(110) premodified with o-anthranilic acid.

The three-dimensional (3D) structure of evaporated Cu atoms on a TiO₂(110) surface premodified with o-anthranilic acid (o-AA) was examined using polarization-dependent total reflection fluorescence X-ray absorption fine structure (PTRF-XAFS) to elucidate the effect of the premodification on the Cu dispersion over the TiO₂(110) surface. Cu was found to be atomically dispersed with the formation of N--Cu--O bonds (where the N is provided by the o-AA and the O is present in the TiO₂ lattice) on the surface, and the factors for controlling the atomic dispersion are discussed.
