摘要：
We have imaged the products of water dissociation on TiO(2)(110) with noncontact atomic force microscopy (NC-AFM). Scanning tunneling microscopy (STM) experiments have revealed that water splits into a hydroxyl group that sits in an O vacancy and an H adatom which lies on a bridging O atom. With this knowledge, STM images acquired in the same area allow an unambiguous identification of these H adatoms in the corresponding NC-AFM images.
