摘要：
Highly dispersed monoatomic Cu species on a TiO2 (110) surface were successfully prepared by a new method in which the TiO2 (110) surface was premodified with a 3-thiophenecarboxylic layer. Polarization-dependent total reflection fluorescence-X-ray absorption fine structure (PTRF-XAFS) showed the three dimensional structure of the monoatomic Cu species which were stabilized on the surface through the formation of Cu-S (adsorbate) and Cu-O (bridging oxygen) bonds.
