摘要：

We have succeeded in imaging individual formate ions adsorbed on TiO2(110)-(1 X 1) by non-contact atomic force microscopy. Formic acid is dissociatively adsorbed on TiO2(110)-(1 X 1) surface at room temperature to give formate ions (HCOO-) which order in a (2 X 1) periodicity at the saturation coverage of 0.5 ML. Thr (2 X 1)-formate overlayer was resolved as ordered bright spots with a rectangular unit of 0.65 X 0.59 nm(2). Dispersed formate ions of lower coverages were also observed as bright spots between the bridging oxygen ridges along the [001] direction. (C) 1997 Elsevier Science B.V.
