摘要：

We have succeeded in STM-imaging of formates adsorbed on TiO2(110) With atomic-scale resolution, formates being regarded as intermediates for catalytic decomposition reaction of formic acid on TiO2(110). Dispersive and (2 x 1)-ordered overlayers of formates were resolved with positive sample bias voltages. The formates were adsorbed on the rows of fivefold coordinated Ti4+ cations along the [001] axis. Their individual images were elongated in the [110BAR] direction. The anisotropic feature reflects the distribution of the tunneling orbital, the LUMO, of the formates.
